Abstract

Methods of synthesizing biaryls using nickel-catalyzed [2+ 2+ 2] cocyclization were developed. Two ways for the synthesis of biaryl using [2+ 2+ 2] cocyclization were investigated: one method is that biaryls synthesized from alkyne having a phenyl group and 2 equivalents of acetylene, and the other method is that those were synthesized from α, ω- diyne having a phenyl group at an α-position and acetylene. The yield is good in each ...
