Pd-Catalyzed α-Arylation of Nitriles and Esters and γ-Arylation of Unsaturated Nitriles with TMPZnCl·LiCl
摘要:
Using TMPZnCl center dot"LiCl as a kinetically highly active base, nitriles and esters undergo a Pd-catalyzed alpha-arylation under mild conditions. Remarkably, in the case of alpha,beta or beta,gamma-unsaturated nitriles, a regioselective gamma-arylation or a gamma-alkenylation is observed.
