Metal Carbonyl-Induced N-O Bond Cleavage of the Oxime Group

Article abstract of DOI:10.1246/bcsj.59.2365

The reaction of or with oxime O-acetate of 1,3-diphenyl-2-propen-1-one undergoes a reductive N-O bond cleavage to give an imine which dimerises and/or is hydrolyzed to ketones.The dimer, so formed, undergoes fragmentations to give pyridine and pyrimidine derivatives.Similarly, the reaction of with several oxime O-acetates, oximes, and an oxime ether were shown to give the corresponding ketones.A reaction of oxime O-acetates with or with to give the corresponding ketones was also shown to proceed very slowly.
