Unusual silver coordination by mono-carboxylate utilization of a poly-carboxylate anion, solid-state structures of silver-tetrachlorophthalate with phthalazine and amine ligands

Silver carboxylate coordination with the tetrachlorophthalate anion, in combination with neutral donor ligands, has been found to deviate from other known poly-carboxylate complexes. Both complexes reported here, bis-[tetrachlorophthalato-silver phthalazine] and bis-[ammino-tetrachlorophthato-silver di-ammino-silver], utilize mixed carboxylate bonding types for silver coordination. In the case of the phthalazine ligand, both chelating and monodentate carboxylates form the framework for the oligomeric structure. In the case of the ammine ligand, one carboxylate forms a monodentate connection to a silver-ammine group, while the other is simply involved with hydrogen bonding to lock in a [(Ag-NH3)2-Ag-NH3] substructure with an adjacent tetrachlorophthalato-silver unit. Both structures exhibit supramolecular connections via hydrogen bonding and pi-pi interactions.

Microwave assisted 1,3-dipolar cycloaddition reactions of 2-(4-halobenzoyl) phthalazinium methylides

The cycloaddition reactions, in liquid and solid phase, of 2-(4-halobenzoyl) phthalazinium methylides to activated alkenes and alkynes by classical heating and under microwaves were studied. The microwave assisted reaction of phthalazinium ylides to activated alkenes and alkynes shows a remarkable acceleration under microwave irradiation and allows the general and facile synthesis. 2-(4-halobenzoyl) phthalazinium methylides show a different behaviour of reactivity in liquid and solid phases and a possible explanation is furnished. A comparative study, microwave-classical heating on the one hand and reactions in liquid and solid phases on the other has been done.

Synthesis and reactions of some novel 4-biphenyl-4-(2H)-phthalazin-1-one derivatives with an expected antimicrobial activity

In this study reaction of 1-(biphenyl-4-carbonyl)benzoic acid ( 1) with hydrazine hydrate, phenyl hydrazine, acetyl hydrazine and benzoyl hydrazine in boiling dry benzene gave the corresponding 4-biphenyl-4-yl-( 2H)-phthalazin-1-one ( 2a-d), respectively. The structure of 2c was established via its reaction with 2-chlorobenzaldehyde, 2-nitrobenzaldehyde in ethanol to give the chalcones 3a,b, respectively. On the other hand, the cyclocondensation of the acid 1 with semicarbazide and thiosemicarbazide in sodium acetate gave phthalazinone amide/thioamide 4a,b, respectively. The reaction of 1 with hydroxyl amine hydrochloride in different media was also studied, to give the oxime derivative 5, which was readily converted to benzooxazin-1-one derivative 6 by boiling in acetic anhydride. Compound 6 was also obtained, when the acid 1 was reacted with hydroxyl amine hydrochloride in boiling pyridine. In addition, the phthalazinone derivative 2a reacted under Mannich reaction condition with phthalimide, morpholine, o-crezole and beta-naphthol to give Mannich bases 7a-d, respectively. The structural assignment of the new compounds was based on analytical and spectral data. And some of the new products showed antimicrobial activity.

Multicomponent reactions: A mighty journey partner for infectious tropical disease drug discovery

Infectious tropical diseases such as malaria, tuberculosis, and the so-called neglected tropical diseases are causing tremendous suffering to millions of people and huge impact on national economies, seriously worsening life conditions in the poorest parts of the world, where these diseases are endemic. Despite the existence of drugs for most of these diseases, they are far from adequate. Lack of efficacy, toxicity, and emergence of pathogen resistance are among the most important flaws of currently available drugs. Thus, apart from improving prevention and vector control measures, there is an urgent need for developing new efficacious, safe, and inexpensive drugs that desirably feature novel chemotypes. Multicomponent reactions (MCRs), where three or more reactants are combined in a one-pot reaction, constitute a very powerful tool for such endeavors, inasmuch as they enable a very rapid access to structurally diverse, usually complex scaffolds, shortening the synthesis of the novel drugs and, hence, lowering production costs, and affording original chemotypes. In this chapter, we provide an overview of the application of different types of MCRs to drug discovery against infectious tropical diseases, with particular emphasis on how structural complexity and molecular diversity can be readily introduced through their use.

Organocatalyzed, Visible-Light Photoredox-Mediated, One-Pot Minisci Reaction Using Carboxylic Acids via N-(Acyloxy)phthalimides

An improved, one-pot Minisci reaction has been developed using visible light, an organic photocatalyst, and carboxylic acids as radical precursors via the intermediacy of in situ-generated N-(acyloxy)phthalimides. The conditions employed are mild, demonstrate a high degree of functional group tolerance, and do not require a large excess of the carboxylic acid reactant. As a result, this reaction can be applied to drug-like scaffolds and molecules with sensitive functional groups, enabling late-stage functionalization, which is of high interest to medicinal chemistry.

Dual-atom Ag2/graphene catalyst for efficient electroreduction of CO2 to CO

Electrochemical reduction of CO2 into value-added carbon compounds offers a promising strategy to mitigate global warming, but present challenges for chemistry due to the poor selectivity and stability of electrocatalysts. In this work, we report a dual-atom Ag2/graphene catalyst featuring well-defined AgN3-AgN3 active site for CO2 electrochemical reduction. This dual-atom catalyst can drive CO2 reduction reaction at a potential as high as -0.25 V, and exhibit excellent CO Faradic efficiency up to 93.4 % with a current density of 11.87 mA cm?2 at -0.7 V and long-term stability, far surpassing the single-atom Ag1/graphene and the traditional silver nanoparticle catalysts. DFT calculations reveal that the dual-atom Ag site lowers the barrier for the formation of *COOH by stabilizing the *CO2 through the concomitant interactions with the C and an O atom of CO2, resulting in excellent catalytic performance.

Cobalt Nanoparticles Apically Encapsulated by Nitrogen-doped Carbon Nanotubes for Oxidative Dehydrogenation and Transfer Hydrogenation of N-Heterocycles

It is important to develop a highly active and stable transition-metal catalyst with dual-functional properties in the reversible transformations between various saturated and unsaturated N-heterocycles. Herein, we prepared the cobalt nanoparticles (Co NPs) apically encapsulated by the N-doped carbon nanotubes catalyst (Co@NCNTs) via a multiple pyrolysis of low-cost dicyandiamide and cobalt (II) acetylacetonate. The catalyst shows excellent activity and recyclability towards the oxidative dehydrogenation (ODH) and the catalytic transfer hydrogenation (CTH) for various N-heterocycles. The structure of outer N-doped carbon nanotubes (NCNTs) can protect Co NPs from aggregation and leaching. Moreover, the encapsulated Co NPs and the NCNTs may generate a synergistic effect. Both of them facilitate the high performance. The poisoning tests with KSCN were to clarify the different active sites for ODH and CTH reactions: the Co NPs could modify the NCNTs through electrons redistribution, therefore the NCNTs could directly activate O2 in ODH. The encapsulated Co NPs is enhanced by the doped N atoms which is good for the H2 activation in CTH. What’s more, the mechanisms of ODH and CTH reactions were also proposed. This work provides a facile and low-cost method to design catalysts, which are dual-functional, highly active and stable, for industrial applications.

Ultrasound assisted reactions of steroid analogous of anticipated biological activities

A new, fast, efficient and general method for preparation of steroid analogous of anticipated biological activity under ultrasound irradiation and classical heating is reported. The reaction pathway involves two steps: quaternization of phthalazine heterocycle followed by a 3+2 dipolar cycloaddition of cycloimmonium ylides to dienophiles. Under ultrasound the reaction time decreases substantially, the yields are higher, the reaction conditions are milder. A comparative study ultrasound verses classical heating has been done.
