Simple and Efficient Procedure for Synthesis of N'-Arylamidines Using Trimethylaluminum

howeverit requires longer reaction time and harsh reaction condition.In 1990, Garigipati reported the conversion of alkyl and arylnitriles to unsubstituted amidines in a single step usingmethylchloroaluminum amide which prepared by additionof ammonum chloride to commercially available trimethyl-aluminum.
