Abstract
A palladium-catalyzed cross-coupling of 3-iodoazetidines and nonheteroaryl boronic acids was reported. The [1,1'-biphenyl]-2-yldicyclohexylphosphane ligand enabled the reaction that favored the formation of 2-aryl azetidines. The control experiments indicated that the reaction can proceed through either a palladium-hydride/dihydroazete complex or free dihydroazete intermediate followed by hydropalladation.

Abstract
The first palladium-catalyzed Hiyama cross-coupling reactions of arylsilanes with 3-iodoazetidine were described. The protocol provides a convenient access to a variety of useful 3-arylazetidines which are of great interest in pharmaceutical laboratories in moderate to good yields (30%-88%). In addition, this strategy has the advantage of easy operation and mild reaction conditions.
