Several Pd(II) complexes with unconventional pyridazine- and phthalazine-derived carbene ligands were synthesized via direct oxidative addition of Cl derivatives of the alkylated diazine heterocycles to Pd(0) species. The alkylated ligand precursors are readily prepared from commercial starting materials, and oxidative addition is regioselective. DFT calculations confirm that the thermodynamically favored products are formed. Four complexes (1-4) have been fully characterized, including by X-ray crystallography. Attractive intramolecular pi-pi stacking between the electron-poor N-alkylated diazine heterocycles and adjacent phenyl groups of the PPh3 coligands is revealed by the solid-state structures.

The reactions were followed under pseudo-first-order conditions as a function of nucleophile concentration and temperature using stopped-flow and UV-Vis spectrophotometric methods. The reactivity of the nucleophiles follows the order TU > DMTU > TMTU. The general order of reactivity for the aqua complexes follows pzn > qzn > pmn > pdn > pht which is confirmed by the obtained pK (a) values and the quantum chemical calculated NBO charges at the metal centre. The negative values reported for the activation entropy confirm the associative nature of the substitution process. The results demonstrate the strong connection between structural and electronic characteristics of the diazine-bridging ligand and reactivity of the dinuclear Pt(II) complexes.

A novel heteropolyanion-based Bronsted acidic ionic liquid material [PhBS](3)PW12O40, butane mono-sulfoacid-functionalized phenanthrolinum salt of phosphortungstate catalyst (PhBS-PW), was synthesized and well characterized with FTIR, H-1 and C-13 NMR, electro-spray ionization mass spectrometry (ESI-MS), EDX and TG analysis techniques. The new prepared catalyst was used for the efficient one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives from a three-component condensation reaction between aromatic aldehydes, dimedone, and phthalhydrazide in H2O under thermal conditions. This green approach has several advantages such as short reaction times, clean reaction profiles, and simple experimental and workup procedures. Moreover, the catalyst can be easily recovered and reused at least nine times with only slight reduction in its catalytic activity with no leaching amount of catalyst into the reaction mixture. These economical factors (time, cost, waste, etc.) for this three-component reaction hold promise for the future of organic synthesis. Graphic abstract In this work we introduced a new efficient Bronsted acidic ionic liquid (BAIL) and then its catalytic activities have been considered in the three-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones via the domino Knoevenagel condensation/Michael addition/intramolecular cyclodehydration sequence in water under reflux condition.
