We have studied the reactions of 3-arylaminobenzofuro-, 3-arylaminobenzothieno-, and 3-arylaminoindolo[2,3-c]pyrylium salts with ammonium acetate, primary amines, and hydrazine hydrate. In an alcoholic medium, primary amines and hydrazine hydrate open up
Acylation and cyclodehydration of benzofuran-, benzothiophene-, and indolyl-3-acetic acid arylamides. Synthesis of novel benzofuro[2,3-c]-, benzothieno[2,3-c], and indolo[2,3-c]pyrilium and pyridine derivatives
