The synthesis of cyclic halooxatelluranes (3a, 4a-d, 5a) has been achieved via dehalogenation of α-halo carbonyl compounds (2A-F) with tellurides (1a-d) containing hydroxy group on the side chain. Halophilicity of the tellurides was compared with that of selenides and a plausible reaction mechanism is discussed.
