Here, we report new methodology for synthesizing 2,3-benzodiazepines and their analogues by means of phosphate-assisted acylation reaction of 1-arylpropan-2-ones with a carboxylic acid followed by hydrazine cyclization in a one-pot two-step manner. An unp

The conversion of 2-benzopyrylium salts to benzanthracenes, which proceeds through prior dimerization of a new type, was observed.An intermediate dimer was isolated, its properties were studied, and assumptions regarding the mechanisms of its formation
