stereoselective reactions of ortho-, meta-, and para-bromobenzyl bromide under Stille and (or) Suzuki cross-coupling reactions are described that provided substituted styrene monomers and biaryls in two steps. By controlling the experimental conditions, the first coupling provided access to allylarene or diarylmethane intermediates, and the second reaction led to the desired styrenes and biaryls, substituted
摘要 描述了在Stille和(或)Suzuki交叉偶联反应下邻,间和对溴苄基溴的区域和立体选择性反应,该反应可分两个步骤提供取代的苯乙烯单体和联芳基。通过控制实验条件,第一偶联提供了进入烯丙烯或二芳基甲烷中间体的通道,第二反应导致了所需的苯乙烯和联芳基,具体取决于原料,在邻位,间位或对位被间隔臂取代。 描述了在Stille和(或)Suzuki交叉偶联反应下邻,间和对溴苄基溴的区域和立体选择性反应,该反应可分两个步骤提供取代的苯乙烯单体和联芳基。通过控制实验条件,第一偶联提供了进入烯丙烯或二芳基甲烷中间体的通道,第二反应导致了所需的苯乙烯和联芳基,具体取决于原料,在邻位,间位或对位被间隔臂取代。
