of styrenes with α‐carbonyl alkyl bromides and arenes for producing highly bulky 1,1‐diarylalkane derivatives has been developed. In this transformations, two new C−C bonds were formed in a single reaction step through C−Br bond cleavage and C(sp 2)−H functionalization. This protocol tolerates a variety of α‐carbonyl alkyl bromides, including primary, secondary and tertiary α‐bromoalkyl ketone esters
已开发出铜和银促进的苯乙烯与α-羰基烷基溴化物和芳烃的分子间1,2-烷基芳基化反应,以生产大体积的1,1-二芳基烷烃衍生物。在这种转变中,通过C-Br键断裂和C(sp 2)-H功能化,在一个反应步骤中形成了两个新的C-C键。该方案可耐受多种α-羰基烷基溴化物,包括伯,仲和叔α-溴烷基酮酯。
