Abstract

Reaction of 1-(2-iodophenyl)-1-methyloxirane (12) with 2 equiv of sodium n-butyltellurolate (n-BuTeNa), generated by the sodium borohydride reduction of di-n-butyl ditelluride, in THF, affords 2, 3-dihydro-3-hydroxy-3-methylbenzo [b] tellurophene (13) in 62% yield, together with a small quantity of 1-(n-butyltelluro)-2-phenyl-2-propanol (27). This transformation presumably involves a tandem SRN1/SHi sequence. Similar reactions of 1-(benzylseleno) ...
