Summary

5,5-Diphenylglycocyamidines bearing an alkyl group in position 3 are partly rearranged to the corresponding N2-alkyl derivatives on heating with alcoholic ammonia in the presence of ammonium acetate. Prolonged heating with ammonium acetate leads to N-dealkylation both of N3- and N2-alkyl derivatives. 5,5-Diphenylglycocyamidine in turn is mono- or dialkylated at N2 on heating with the acetates of primary and secondary amines respectively. A mechanism for these reactions is proposed.
