Sažetak

A perturbational molecular orbital (PMO) treatment has been
developed for the title 1,3-cycloaddition reactions. Molecular orbitals
were computed by the CND0/2 method. The results obtained at
different levels of approximation of the PMO theory are presented.
The regiochemistry is also discussed on the basis of the charge
transfer model by using EA's and IP's.
