Reactivity and Mechanistic Studies of the Reactions of Chlorodiphenylphosphine and Its Oxide with Methyl Glyoxylate,Glyoxylate Oximes,and Methyl Cyanoformate

In this work, we describe the reactivity of chlorodiphenylphosphine and its oxide, as well as diphenylphosphine, with some glyoxylate derivative systems: methyl glyoxylate, methyl or 8‐phenylneomenthyl glyoxylate oximes, and methyl cyanoformate. By analyzing the reactions outcomes and with the aid of computational chemistry, we propose some reaction mechanisms and molecular rearrangements.
