A Bench-Stable Catalyst for the Rapid Hydrophosphination of Activated and Unactivated Alkenes

Abstract

Cu(acac)<sub>2</sub> (<b>1</b>) is a highly active catalyst for the hydrophosphination of alkenes. Photocatalytic conditions are critical, which provde high conversions with unactivated substrates that have never before been reported with an air-stable catalyst or at ambient temperature. The simplicity of compound <b>1 </b>places hydrophosphination in the hands of more synthetic chemists.<br>
