Synthesis of 2-Phenoxy-2,2′(3H,3′H)-spirobi[1,3,2-benzoxazaphosphole]Synthesis, 1980
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 PN and PO bonds (instead of a PC 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.
