Abstract

Tetracoordinated derivatives of 2-halo-2-aryl-5H-1.2-oxatelluroles and 1-halo-1-butyl-3H-benz-2.1-oxatelluroles were synthesized by the oxidation of 3-aryltelluro-2 propen-1-ols and the dehydrogenation of 2-butyldihalotellurobenzyl alcohols. The halogen atoms in these compounds are readily replaced in nucleophilic substitution reactions. The reaction of benzoxatelluroles with bromine is accompanied by cleavage of O-Te bonds and leads, depending on the nature of the substituent at C(3), to 2-(butylbromotelluro)benzaldehyde or 2-(butyldibromotelluro)benzophenone.
