Reaction of the 1,2-disilylene, [ArC(NDip)2 Si]2 1 (Dip=2,6-diisopropylphenyl, Ar=4-C6 H4 But ), with CO proceeds via insertion of CO into one Si-N bond, and Si-Si bond cleavage, to cleanly give the bis(silylene), ArC(NDip)2 Si()O C S i ( ) ( N D i p ) 2 C ‾ Ar 2, under ambient conditions. The reaction can be partially reversed when solutions of 2 are subjected to UV irradiation. The five-membered heterocyclic fragment of 2 represents the first silicon analogue of an "abnormal" N-heterocyclic carbene (aNHC), a view which is s
