Efficient new methodology of regio- and stereoselective synthesis of a variety of functionalized mono- and polycyclic compounds based on thio- and selenophosphates is reported. The representative examples of these compounds are: vinyl thiiranes, conjugated dienes, cycloadducts, _,_-unsaturated carbonyl compounds, allylic alcohols, _-hydroxy ketones and aromatic compounds.
The reaction of selected allylic alcohols with methanol, ethanol, n-propanol, isopropanol and tert-butanol in the presence of catalytic amounts of cerium(III) chloride are described. Allylic alkyl ethers, bis-allylic ethers and 1,3-dienes were obtained depending on the structure of the reacting alcohols .
