One-pot borylation-allylation reactions of aldehydes and allylic alcohols were performed under various reaction conditions. The borylation of allylic alcohols was performed using a very efficient SCS palladium pincer-complex catalyst. The regioselectivity of the allylation depends on the applied solvent. The reaction in CHCl3 gave the linear allylic product; however, when MeOH was added to the reaction mixture, the branched allylic product was formed.
醛和烯丙醇的一锅硼化-烯丙基化反应在各种反应条件下进行。烯丙醇的硼化反应使用一种非常高效的SCS钯钳形配合物催化剂进行。烯丙基化反应的区域选择性取决于所使用的溶剂。在CHCl₃中反应得到线性烯丙基产物；然而，当向反应混合物中加入甲醇时，则形成支链烯丙基产物。
