We report a Rh-catalyzed hydrothiolation of 1,3-dienes, including petroleum feedstocks. Either secondary or tertiary allylic sulfides can be generated from the selective addition of a thiol to the more substituted double bond of a diene. The catalyst tolerates a wide range of functional groups, and the loading can be as low as 0.1 mol %.
我们报告了 1,3-二烯(包括石油原料)的 Rh 催化氢
硫醇化反应。通过将
硫醇选择性加成到二烯的更多取代的双键上,可以生成仲烯丙基
硫化物或叔烯丙基
硫化物。该催化剂可耐受多种官能团,负载量可低至 0.1 mol%。
