A new way is presented to prepare group 14 compounds substituted with a terminal NHC stabilized phosphenidenyl substituent. On this occasion, it is shown that depending on the chain length of the group 14 element dichlorides in reaction with SIMesPK a mono- or disubstitution can be observed. Starting from Me2SiCl2 or tBu(2)SnCl(2) a single substitution occurred. Longer chains of group 14 dihalides like (SiMe2Cl)(2) or O(SiMe2SiMe2Cl)(2) lead to silicon bridged bisphosphinidenyl compounds.
