It is shown that industrially available 2,3-dichloro-1,3-butadiene is a useful starting material for the synthesis of 2,3-diaryl-1,3-butadienes. Ni(II)-catalyzed cross-coupling reaction of 2,3-dichloro-1,3-butadiene with ArMgBr (Ar = 2-thienyl, phenyl, 4-dodecyloxyphenyl, and 4-fluorophenyl) gives the corresponding 2,3-diaryl-1,3-butadienes in good yields.
研究表明,工业上可获得的2,3-二氯-1,3-丁二烯是合成2,3-二芳基-1,3-丁二烯的有用起始材料。Ni(II)催化的2,3-二氯-1,3-丁二烯与ArMgBr(Ar = 2-噻吩基、苯基、4-十二烷氧基苯基和4-氟苯基)的交叉偶联反应可以在良好产率下得到相应的2,3-二芳基-1,3-丁二烯。
