Abstract
The reaction of diphenyl diselenide with [bis(trifluoroacetoxy)iodo]benzene followed by the addition of 2-allylphenol gave 2-phenylselenomethyl-2,3-dihydro-benzofuran in 82% yield. The reaction of phenylselenenyl chloride with N-tosyl-2-isopropenylanilide followed by the addition of m-CPBA afforded N-tosyl-3-methylindole in 68% yield. Interestingly, the reaction of diphenyl diselenide with [bis(trifluoroacetoxy)iodo]benzene followed by the addition of 2-isopropenylaniline gave 4-methyl-4-phenylselenomethyl-2-trifluoromethyl-3,1-benzooxazine in 65% yield.
