Different synthetic approaches to functionally substituted benzylamines were examined: reductive amination of alkyl aryl ketones and reduction of aromatic aldehyde oximes. The most efficient procedures were used to prepare a series of previously unknown hydroxy-, alkoxy-, and halogen-substituted benzylamines.
4-nitro-1-((trifluoromethyl)sulfonyl)-imidazole (NTSI), slight modifications of reaction conditions resulted in significantly different reaction paths to provide either nitriles or isonitriles. The challenging conversion of aldoximes into isonitriles was achieved under mild conditions.
