The reaction of tris(trimethylsilyl)methylboron dihalides (Me3Si)3CBX2 (X = Cl, F) with the lithium phosphides LiPHtBu and LiPHmes leads to the phosphinoboranes (Me3Si)3CBX-(PHR), (Me3Si)3CB(PHR)2 or the 1,3,2,4-diphosphadiboretanes [(Me3Si)3CB(PR)]2

A series of benzo- 1,3,3-diphosphaborolanes C6H4(PR)2BR' (R = H, iPr, SiMe3; R' = R2N, R) has been prepared by several routes and characterized by spectroscopic and – in part – by X-ray diffraction methods. They feature pyramidal P atoms with the
