supporting information; experimental part, p. 8881 - 8885 (2012/10/08)

Ring expansion of NHCs! The reaction of N-heterocyclic carbenes (NHCs) with hydrosilanes Ph4-nSiHn (n=1, 2, 3) results in complete rupture of the heterocycle and silylene insertion into one of the C-N bonds of the carbene (see scheme
