A stepwise process involving initial carbon-carbon bond formation leading to a betaine intermediate was proposed for the formal [2+2] cycloaddition. Alternatively, the 1,2-azaphosphetane intermediate can be generated directly through a four-center transition state analogous to that suggested for the Wittig reaction (see refs 2b, 2c, and 3)

1 group, and Ar group contribute to the stereoselectivity for the formation of the 1,2-azaphosphetane intermediate leading to an alkene product. Since the electronic and steric properties of an aryl group, alkenyl group, and alkyl group are significantly different from each other, it is plausible that each type of imine shown in Table 2 needs a different N -sulfonyl group to control the stereoselectivity synergically in its olefination reaction with a benzylidenetriphenylphosphorane
