2RCH (SePh) CHRN3+ PhI+ 2NaOAc spectra. In the case of styrene the other regioisomer 11 could be obtained from the reaction of diphenyl diselenide, sodium azide, and m- nitrobenzenesulfonyl peroxide in a~ etonitrile.~ Reduction of 1 and 11 with LiAlH, in THF afforded the amino derivatives 12 and 13, respectively. The NMR data of compounds 1 and 11, as well as those of 12 and 13 (see Experimental Section), were in agreement with the ...
