Under these ideal reaction conditions, main application of this process was determined by using different arylhydrazines. As a result, a big quantity of phenylhydrazine hydrochloride complexes that incorporate electron-donating and electron-withdrawing groups into the ortho-, meta-, and para-positions produced the required products in perfect yields. The ortho-substituted phenylhydrazine hydrochlorid reacted easily to produce the required product in good yields. The use of 2,4-dichlorophenylhydrazine hydrochloride and 4-bromophenyl-hydrazine
Hydrochloride make this reaction High chemoselectivities. To more demonstrate the efficacy of this reaction, the study of pyridine substrates was surveyed briefly. For instance, the reaction between 4-methoxyphenyl-hydrazine
