The highly diastereoselective dicarbofunctionalization of substituted olefins still remains a daunting challenge in synthetic chemistry. Herein, we report a Pd-catalyzed diastereoselective 1,1-diarylation of 1,1-diarylethylene with chelation group free to enable the modular synthesis of smart material candidates, 1,1,2,2-tetraarylethanes (TAEs), which represent the first protocol by assembling four
取代烯烃的高度非对映选择性二碳官能化仍然是合成化学中的艰巨挑战。在此,我们报告了钯催化的 1,1-二芳基乙烯的非对映选择性 1,1-二芳基化反应,该反应不含螯合基团,从而能够模块化合成智能材料候选物 1,1,2,2-四芳基乙烷 (TAE),它代表了第一个方案是将四个不同的芳基组装成乙烷基序。初步机理实验表明,原位生成的关键 Pd-H 物质在反应过程中不会从烯烃中间体中脱离。
