NOESY spectra. The regio and stereospecificity of the process can be explained by the fact that the reaction proceeds via the intermediate selenirenium ion А, which is attacked by the chloride ion at the sterically unshielded terminal car bon atom. Thus, we showed for the first time the possibility of annulation of the selenium containing heterocycles to the benzene ring based on the reaction of selenium

Highly chemo-, regio-, and stereoselective syntheses of novel organoselenium compounds from selenium dichloride or dibromide and unsaturated ethers are described. The reactions of selenium dichloride with allyl and propargyl phenyl ethers afford either annulated products or bis-adducts depending on the conditions. The first examples of annulation of 3-chloromethyl- and 3-chloromethylene-2,3-dihydro-1
