The cycloaddition reaction of FCH=C=O and NH2CH=NH leading to 2-azetid
inone was studied theoretically at the level of RHF/6-31G and RHF/6-31
G. Two possible mechanisms via a gauche or trans intermediate were co
mpared. The obtained results show that the reaction proceeds in a gauc
he manner much easier than in a trans one. (C) 1996 John Wiley & Sons,
