Investigating the Reaction of <i>N</i>-Carbobenzoxy-<i>O</i>-carbobenzoxy- hydroxylamine with Dimethyl Sulfoxide: Formation of <i>S,S</i>-Dimethyl-<i>N</i>-[(phenylmethoxy)- carbonyl]sulfoximine

N-Carbobenzoxy-O-carbobenzoxyhydroxylamine (1a) underwent a thermally induced reaction in DMSO in which there is net N-α-eliminative oxidation with tandem oxidative incorporation of DMSO to yield S,S-dimethyl-N-[(phenylmethoxy)carbonyl]sulfoximine. Mechanisms for the formation of the sulfoximine are presented as well as the product characterizations, including the X-ray crystal structure.
