Pd-catalysed arylation of propan-1-ol and derivatives: oxidative role of the arylating agent

Abstract

With excess PhI under Pd catalysis, 1-PrOH was converted to a mixture of 3,3-diphenylpropenal and trans-2,3-diphenylpropenal by a concerted, oxidative sequence that involved two arylative couplings and an olefinic aldehyde that was generated in situ.
