An NHC–phosphinidenyl as a synthon for new group 13/15 compounds†
Abstract
The parent phosphinidene SIMesPH (1) (SIMes = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene) was treated with benzyl potassium to form the metalated species SIMesPK (2), which was used as a synthon for the new group 13/15 cycles and cage compounds [SIMesPGatBu2]2 (3), [SIMesP(GatBu2)2Cl] (4) and [K(SIMesP)3AltBu] (5).
