资源简介：
The
reaction of the N-heterocyclic dicarbene (NHDC) [:C{[N(2,6-Pri2C6H3)]2CHCLi(THF)}]n with iodomethane, in a hexane/THF mixture,
affords the ylidic N-heterocyclic olefin NHCCH2 (1; NHC = :C{N(2,6-Pri2C6H3)CH}2) in high yield.
The reaction of 1 with BBr3 in hexane gives
the neutral compound NHC–CH2:BBr3 (2), which in THF unexpectedly converts to the borenium salt
[NHC–CH2:B{O(CH2)4Br}2]+[Br]− (3) through
ring opening of THF.
