资源简介：
Reaction
of bis-(2,6-diisopropylphenyl)-imidazol-2-ylidene
borane with dimethyl acetylenedicarboxylate gives 80% yield of a stable
borirane (boracyclopropane) formed by formal double hydroboration
along with 5% of the (E)-alkenylborane. DFT calculations
suggest a mechanism where divergence to the two products occurs after
a common initial stage of hydride transfer from the NHC-borane to
the acetylenedicarboxylate.
