A Convenient Synthesis of 1-Alkyl-1-phenylhydrazines from N -Aminophthalimide

Abstract N-Alkylaminophthalimides were synthesized by condensation of N-aminophthalimide with aldehydes, and subsequent reduction of the intermediate with pyridine-borane in acetic acid. N-Phenylation and removal of the phthalimide group gave 1-alkyl-1-phenylhydrazines in high yield.

A new intramolecular migration of the imino group of O-arylketoximes to the aryl group under the Beckmann condition

Abstract ZrCl 4 -mediated decomposition of O -arylketoximes in benzene leads to regioselective intramolecular migration of the imino group from the oxygen to the ortho position of the aryl group via electron-deficient nitrogen intermediates.

NEW METHOD FOR THE SYNTHESIS OF NITRILES FROM O-ARYLALDOXIMES WITH ZrCl4

ABSTRACT Nitriles were readily synthesized from the corresponding O-phenyl- or O-(p-cyanophenyl)-aldoximes with ZrCl4 in nitromethane or in benzene.

AlCl3-mediated migration of the benzamido group of N-phenoxybenzamide derivatives to the phenyl group

AlCl3-mediated decomposition of N-phenoxybenzamide derivatives in dichloromethane mainly leads to regioselective intramolecular migration of the benzamido group from the oxygen to the ortho position of the phenyl group via electron-deficient nitrogen intermediates.
