N-Heterocyclic carbenes are shown to cleanly abstract dihydrogen from organotin di- and trihydrides to intermediately form the reactive stannylene species [R2Sn] and [R′SnH], respectively, as well as the corresponding dihydro imidazole [R = Ph, trip: 2,4,6-triisopropylphenyl; R′ = trip, Ar*: 2,6-bis(2′,4′,6′-triisopropylphenyl)phenyl]. Depending on the molar ratio of the carbene, these intermediates undergo further reactions to form tetraorgano distannanes and carbene adducts in excellent yields. Since the side products can be removed as volatiles, the method offers a facile, clean and high yielding route to stannylene derivatives with strongly decreased steric protection compared to previously known compounds. On stoichiometric reaction hydrogen was completely removed from an organotin trihydride and a novel tin cluster with overall composition R6Sn6 (R = trip) was structurally characterized.
