Functionalized allylsilanes 1-5 and aldehydes 6-8 undergo Lewis-acid mediated ring closure to afford 2,3,5-or 6-substituted tetrahydropyrans (8-15) and 2,3-substituted octahydrochromenes (16a-b) with excellent stereoselectivity. According to DFT calculations the high stereoselectivity arises from el

Molecular orbital calculations were carried out for the dimerization step in the polymerization process of vinyl acetate and styrene through free radicals and ionic mechanisms. The calculations were performed for monomers, dimers, their positive and negative ions, and free radicals. The minimum-ener
