Lying low : A lithiated unsubstituted N‐heterocyclic carbene (NHC) boryl anion can be generated by reduction, and trapped by electrophiles (see scheme; dipp=2,6‐diisopropylphenyl) to provide new substituted NHC boranes. It is yet another example of a low‐valent boron compound or boron‐containing reactive intermediate stabilized by an NHC, thereby extending the scope of NHC borane chemistry.
