资源简介:
Monohydroboration of substituted 1,3-diynes with an N-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.
