Notizen:
The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (-78°C, O°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 reaction temperature. PhSeCl has been found to be more efficient than PhSeBr in the cyclization reactions.
