An efficient Ni(COD)₂/dppf catalyzed olefination of Ar–O–TCT as synthetic equivalents of aryl halides is described. Activation of C–O bonds in phenols as readily available compounds was achieved with 2,4,6-trichloro-1,3,5-triazine (TCT). This method provides practical access to 1,2-disubstituted olefins in high yields and high functional group compatibility.

2,4,6-三氯-1,3,5-三嗪（TCT）保护的酚的高效Ni催化转化为烯烃

描述了一种有效的Ni（COD）₂ / dppf催化Ar–O–TCT的烯化反应，作为芳基卤化物的合成等价物。用2,4,6-三氯-1,3,5-三嗪（TCT）实现了苯酚中C-O键作为现成化合物的活化。该方法提供了高产率和高官能团相容性的实际获得1,2-二取代烯烃的途径。
