A facile synthesis of aryl vinylphosphonates has been based on Heck reaction of aryldiazonium salts bearing electrowithdrawing or donating groups with vinylphosphonates. A one-pot procedure consisting of Heck reaction and hydrogenation permits the clean formation of useful Wadsworth-Emmons reagents.
