Nickel-catalysed hydroarylation of alkynes using arylboron compounds: selective synthesis of multisubstituted arylalkenes and aryldienes

Abstract

Bis(1,5-cyclooctadiene)nickel was found to be an effective catalyst for the addition of the aryl group of arylboron compounds to alkynes in the presence of a proton source, which gives various multisubstituted alkenylarenes or dienylarenes selectively.
