Whereas aryl(trialkyl)silanes are considered to be ideal organometallic reagents for cross‐coupling reactions owing to their stability, low toxicity, solubility, and easy accessibility, they are generally inert under typical cross‐coupling conditions. Disclosed herein is a palladium/copper catalytic system that enables the cross‐coupling of trimethyl, triethyl, tert‐butyldimethyl, and triisopropyl
鉴于芳基(三烷基)硅烷的稳定性,低毒性,溶解性和易接近性,它们被认为是用于交叉偶联反应的理想有机金属试剂,但它们通常在典型的交叉偶联条件下呈惰性。本文公开了钯/铜催化体系,该体系可使三甲基,三乙基,叔丁基二甲基和三异丙基芳基硅烷与芳基溴化物交叉偶联。此过程适用于噻吩的连续CH和C-Si键芳基化以及聚(噻吩-芴)的合成。
