Iron-catalysed Suzuki coupling? A cautionary tale

WebThe significant progress made in the context of iron-catalyzed cross-coupling reactions in the past several years has boosted competition with well-known nickel and palladium catalyst systems. Iron-catalyzed protocols not only benefit from economic and toxicology standpoints, but also exhibit a range of reactivities and tolerate many functional groups. … WebOrganoboron reagents are particularly useful, and accordingly there has been great progress in the development of iron-catalysed Suzuki cross-coupling reactions. However, the cross-coupling between an aryl halide and aryl boron reagent, a Suzuki biaryl cross-coupling, has not yet been achieved with iron-catalysis under mild conditions. dwayne johnson cfl https://amythill.com
