Silylene is a chemical compound with the formula SiH2. It is the silicon analog of methylene, the simplest carbene. Silylene is a stable molecule as a gas but rapidly reacts in a bimolecular manner[clarification needed] when condensed. Unlike carbenes, which can exist in the singlet or triplet state, silylene (and all of its derivatives) are singlets.

Silylenes are formal derivatives of silylene with its hydrogens replaced by other substituents.[2] Most examples feature amido (NR2) or alkyl/aryl groups.[3][4] Silylenes have been proposed as reactive intermediates. They are carbene analogs.[5]
