Transition Metal Catalysed C-S Cross-Coupling Reactions at Room Temperature.

摘要

Transition metal catalysed formation of Csp2-S bond through cross-coupling reaction stands important and powerful tools in synthetic organic chemistry. The reaction constitutes an important strategy for the synthesis of thioethers that possess diverse biological activities in medicine and agriculture. Nonetheless, maintaining reaction temperature during Csp2-S cross-coupling reaction decides fate of desired product along with possibility of by-product and disulfides. The economy of process, safety and environmental issue demands thioether synthesis at mild condition and room temperature. Only very few reactions were successful under mild condition using Pd, Cu, Ni, Ni-Ir and Ir catalyst. The current prospective summarizes the best protocols used for efficient Csp2-S cross-coupling reactions by transition metal catalyst under mild condition.
