Triphenylphosphine-catalyzed isomerization of alkynyl ketones in aqueous solution

Department of Chemistry, University of Science and Technology of China, Hefei 230026, China

Received Date: 9 April 2007

Fund Project: We express our appreciation to NNSFC (no.20572104).

An efficient isomerization of alkynyl ketones to (E, E)-diene ketones was developed. The reaction catalyzed by 20 mol%triphenylphosphine in aqueous media gave the desired products in good yields.
