THE STRUCTURE AND A NEW METHOD FOR THE SYNTHESIS OF THE DIMER OF 2,2-DIPHENYL-1,3,2-BENZOXAZAPHOSPHOLE
Chekhlov, A. N.,Bovin, A. N.,Tsvetkov, E. N.
, p. 850 - 853 (1990)
X-ray diffraction structural analysis established the structure of the dimer of 2,2-diphenyl-1,3,2-benzoxazaphosphole with a pentacoordinated phosphorus atom.A new method is proposed for the preparation of this dimer.
A New Reaction of Penta-co-ordinate Phosphorus Derivatives: the Formation of Phosphinates from an Oxazaphosph(V)ole and Carbonyl Compounds
Cadogan, J. I. G.,Husband, James B.,McNab, Hamish
, p. 1054 - 1055 (1981)
The oxazaphosph(V)ole (1) reacts with neat carbonyl compounds (aldehydes, ketones, and formamides) to give the phosphinates (2); in solution, a benzoxazole is formed in one case.
A SIMPLE SYNTHESIS OF DIMERIC 2,2-DISUBSTITUTED 1,3,2-BENZOXAZAPHOSPHOLES FROM PHOSPHORYL PIV-COMPOUNDS

Dimeric 2,2-disubstituted 1,3,2-benzoxazaphospholes were prepared from o-aminophenyl phosphinates, phosphonates or phosphate by dehydration with PPh3/CCl4- or Ph3PBr2-reagents.
The Reactivity of Organophosphorus Compounds. Part 36. Pyrolyses of 2-Alkoxy-2,3-dihydro-1,3,2-benzoxazaphosph(V)oles

, p. 1449 - 1453 (2007/10/02)
Thermolysis of the phosph(V)oles in the solid state, in suspension, or in solution, gives the 'phosphole dimer' (6) via dimerisation of the phosphinimine (7).This species, generated from the phosph(V)ole (3), or from the dimer (6), may be trapped by carbonyl compounds (aldehydes, ketones, or formamides) to give the phosphinates (8).Reaction with p-nitrobenzaldehyde converted the phosph(V)ole (3) into the benzoxazole (13).
