AB - The reaction of N,N,O‐tris(trimethylsilyl)‐o‐aminophenol with two equivalents of phosphinic chloride yielded dimeric 2,2‐disubstituted 1,3,2λ5‐benzoxazaphospholes and trimethylsilyl phosphinate. The chlorides having the bulk substituents (o‐chlorophenyl or tert‐butyl) at phosphorus or containing PN and PO bonds (instead of a PC bond) either didn't react at all or reacted to retain the phosphoryl group. Being stable in solution at 20°C, the individual diastereoisomers of dimeric 1,3,2‐benzoxazaphospholes were converted upon warming to an equilibrium mixture of isomers. When reacted with another dimer each gave a mixed dimeric compound having two different phosphorus atoms in the molecule.
