Abstract: Reaction of carbene-stabilized disilicon L: Si=Si:L (L: = :C{N(2,6-Pri2C6H3)CH}2, 1) with BH3 · THF results in facile cleavage of the silicon-silicon double bond and the formation of two quite different "push-pull" stabilized products with borane-and carbene-coordinated silylene moieties: 2, containing a parent silylene (:SiH2); and 3, containing a unique three-membered cyclosilylene.
