Abstract
The effect of the nature of the heteroatom, annelation, the position of the methylene group, and the character of the substituent on expansion of the ring of heterofulvene cations was investigated on the basis of the bonded variant of perturbation theory within the framework of the π-electron approach. The rearrangements of 1-methylene-3-oxoisofuran, 2-methylene-3-oxobenzofuran, and N-methyleneisoxazole ylid were also examined. The results of the calculations are in agreement with the experimental data.
