Berylliant! Interaction of a well-defined adduct of MeBeH and an N-heterocyclic carbene (NHC) with PhSiH3 results in complete rupture of the heterocycle, and activation of the NHC through effective BeH2 insertion into a C[BOND]N bond of the heterocycle (see scheme; Ar=2,6-diisopropylphenyl, IPr=1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene).
