Abstract
In situ generated aryl, heteroaryl, alkyl, or benzylic polyfunctional zinc reagents obtained by the addition of zinc and LiCl to the corresponding organic iodides undergo smooth Pd(0)-catalyzed Negishi coupling reactions with aryl bromides, chlorides, and triflates in the presence of PEPPSI as a catalyst to produce crosscoupled products in high yields.
