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
