The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (-78 deg C, 0 deg C and room temperature) is investigated.It has been found that Δ4- and Δ5-alkenols are converted into five- and/or six-membered cyclic phenyl selenoethers, the yield of which decreases with increasing temperature.PhSeCl has been found to be more efficient than PhSeBr in the cyclization reactions. Key Words: Olefinic alcohols / Cyclofunctionalization / Benzeneselenenyl halides
