The alkaline hydrolyses of N1-benzoyl-N1,N2-diarylacetamidine (V) and N1-tosyl-N1,N2-diarylacetamidine (IX) were examined.In the hydrolysis of V, hydroxide ion attacked the amide carbonyl carbon to form N1,N2-diarylacetamidine and benzoic acid.In the hydrolysis of IX, hydroxide ion attacked the amidine carbon, and elimination of the N-tosylarylamino group and arylimino group proceeded in parallel, with that of the latter predominating.The alcoholysis reaction of V proceeded without any added catalyst, in contrast to the case of 1-(N-benzoylarylamino)-3-arylimino-1-propene.A unique peak corresponding to the loss of 64 mass units (sulfur dioxide) was observed in the mass spectrum of IX.Keywords - alkaline hydrolysis; alcoholysis; N1-benzoyl-N1,N2-diarylacetamidine; N1-tosyl-N1,N2-diarylacetamidine; 1,1-bis(N-benzoylarylamino)ethene; MS

The addition of aromatic amines to terminal acetylenes in the presence of catalytic amounts of mercury(II) chloride gives imines, enamines, and 1,2,3,4-tetrahydroquinoline derivatives; mercury(II) acetate shows considerably less catalytic activity and may be used for the non-catalytic preparation of imines, enamines, N,N'-disubstituted acetamidines, and N,N-disubstituted acetamides.
