A Ph
3PN-substituted silirane was synthesized, representing a “masked” silylene. Aside from the reactivity toward small molecules, also the migratory insertion of olefins into an intramolecular Si-Si bond was investigated. By additionally preparing PhMe
2PN- and (
tBu)
3PN-based siliranes, a comparative study was set up, analyzing the steric and electronic properties of the three masked silylenes. A correlation between the structure of the ligand and the properties of the respective silylene could be found with the help of Tolman’s “steric and electronic map”.
