The Reactivity of Organophosphorus Compounds. Part 36. Pyrolyses of 2-Alkoxy-2,3-dihydro-1,3,2-benzoxazaphosph(V)oles

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).
