Azolium salts as effective catalysts for benzoin condensation and related reactions

Article abstract of DOI:10.3987/COM-95-7311

A catalytic ability of several azolium salts for benzoin condensation, the benzoylation of 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine, and oxidative aroylation was examined. We found that azolium salts having an imidazolium moiety, such as 1,4-dimethy
