In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 253-52-1, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 253-52-1, name is Phthalazine. In an article£¬Which mentioned a new discovery about 253-52-1
New pyrrolo[2,1-a]phthalazine derivatives by 1,3-dipolar cycloaddtion reactions
The esters of pyrrolo[2,1-a]phthalazine-1,2-dicarboxylic acid 13a-c were obtained from pthalazinium bromide 9, esters of acetylenedicarboxylic acid, triethylamine and tetrakis-pyridinocobalt(II) dichromate (TPCD) as oxidant The synthesis of pyrrolo[2,1-a]phthalazine-1-carboxylic esters from 9, acetylenemonocarboxylic acid esters and triethylamine was performed in the absence of TPCD. Structure proof for the new compunds is based on H-, C-NMR, COSY and Hetcor experiments.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 253-52-1, help many people in the next few years.Recommanded Product: 253-52-1
