| Abstract: | Formation of Formimidoyl Derivatives from Amines and Benzylisocyanide; A New Possibility of Umpolung for Certain C-Atoms Cu(I)Cl can give a colorless and well-crystallized complex with 4 molecules of benzylisocyanide. This complex is able to transfer the benzylisocyanide ligands to primary and secondary amines and to form N-benzylformimidoyl derivatives. Catalyic hydrogenolysis removes the benzyl group, and free formimidoyl compounds are obtained in good yield. The method which succeeds with aliphatic amines, could not be applied to the secondary amino group of tetrahydropterines. |
