| Abstrakt: |
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. |
