Conversion of aldehydes and ketones into chloro-olefins and acetylenes using chloroiodomethane as a chloromethylene source

Abstract

Chloroiodomethane smoothly reacts with triphenylphosphine to yield chloromethyltriphenylphosphonium iodide (1), which in turn can be utilized for the conversion of aldehydes and ketones into chloro-olefins and acetylenes upon treatment with potassium t-butoxide.
