imine derivatives with functionalized aryl pronucleophiles is reported. The aryl nucleophiles are released from silicon-protected aryl-substituted diazenes by desilylation with potassium trimethylsilanolate concomitant with the loss of dinitrogen. A broad range of functional groups is tolerated in the aryl nucleophile but, depending upon their electronic effect, require specific groups at the imine
报道了一种无过渡金属的方案,用于N -苯基 - 和N -苯甲酰基取代的苯甲醛衍生亚胺衍生物与功能化芳基亲核试剂的芳基化。芳基亲核试剂通过用三甲基硅烷醇钾进行脱甲硅烷基化并伴随二氮的损失从硅保护的芳基取代的二氮烯中释放出来。芳基亲核试剂可容许多种官能团,但根据它们的电子效应,亚胺氮原子上需要特定的基团。
