在经典的Pd催化的Stille交叉偶联反应中,由于缓慢的金属转移而产生的Cine取代偶尔会发生在空间受阻的乙烯基锡组分的交叉偶联反应中。总结了这种“反常”交叉偶联模式的机理解释以及金属铜物种在恢复IPSO选择性方面所起的有趣的共同催化作用。还展示了这种独特的铜效应的典型合成应用和铜催化的Stille型交叉偶联的出现。
cine Substitution arising from slow transmetallation occasionally occurs in classic Pd-catalyzed Stille cross-coupling reactions with sterically hindered vinyltin components. Mechanistic explanations of this "abnormal" cross-coupling mode and the intriguing co-catalytic effects of metallic Cu species in restoring the ipso selectivity are summarized. Typical synthetic applications of this unique Cu effect and the advent of Cu-catalyzed Stille-type cross-coupling are also demonstrated.
