以偶氮引发剂(如ACCN和AIBN)和硫醇作为极性反转催化剂,在自由基条件下,取代的1,3-二炔与ann -杂环碳硼烷(nhc -硼烷)发生单硼氢化反应。该反应具有高度的区域选择性和立体选择性,并提供稳定的NHC-(E)-炔基烯基硼烷。
Monohydroboration of substituted 1,3-diynes with anN-heterocyclic carbene borane (NHC–borane) occurs under radical conditions using an azo initiator, such as ACCN and AIBN, and a thiol as a polarity-reversal catalyst. The reaction is highly regio- and stereoselective and provides stable NHC-(E)-alkynylalkenylboranes.
