The reaction of 1-phenylselenocyclopropylmethanols with TsOH in methanol proceeded smoothly to afford the homoallylic ethers, ring-enlargement products, and ring-opening products depending upon the kind of substituent on the cyclopropane ring or α-carbon. On the other hand, in the case of the absence of methanol as nucleophile, 4H-selenochromene derivatives were obtained exclusively.
