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
开发了利用镍催化的[2 + 2 + 2]共环合成联芳基的方法。研究了使用[2 + 2 + 2]共环化合成联芳基的两种方法:一种方法是由具有苯基和2当量乙炔的炔烃合成的联芳基,另一种方法是由α,ω合成的联芳基在α位具有苯基的乙二炔和乙炔。在每种情况下,产率都很高。
