[reaction: see text] Upon attempted silaboration of acyclic 1- and 1,4-substituted 1,3-dienes, a new disproportionation reaction was discovered, yielding 1:1 mixtures of allylsilanes and dienylboranes. It was demonstrated that, as a key step in this new catalytic process, hydrogen is being transferred from one diene moiety to another.
[反应:见正文]在尝试对无环的1和1,4-取代的1,3-二烯进行硅烷化时,发现了新的歧化反应,生成了烯丙基硅烷和二烯基硼烷的1:1混合物。已证明,作为该新催化过程中的关键步骤,氢正在从一个二烯部分转移到另一个。
