Intramolecular reactions between isocyano and iminophosphorane functions yield species containing an embedded 1,3,2-diazaphosphetidine ring, as result of the [2 + 2] cycloaddition primary reactive product, cyclic carbodiimide, with a second unit reactant. DFT studies reveal first rate-determining step entailing 1] involving isocyanide carbon atom P═N double bond, further intervention dipolar precursor intermediate carbodiimide. The ring final products is shown to be hydrolytically thermally labile.
