摘要：

Benzenetellurinyl trifluoromethanesulfonate in conjunction with acetonitrile underwent an E-stereoselective amidotellurinylation reaction with alkynes, but the addition products from terminal alkynes tended to isomerize thermally to (Z)-beta-acetamidovinyl phenyl telluroxide, whereas those from internal alkynes were transformed into oxazoles via a spontaneous intramolecular cyclization.
