Patent number: 4370497Abstract: The present invention relates to the use of telluroxides as mild and selective oxidizing agents serving to oxidize certain functions, notably >C.dbd.S groups, in the presence of other relatively easily oxidized functions which remain unaffected; telluroxides of interest as oxidizing agents include, for example, compounds of the formula: ##STR1## wherein R and R.sup.1, which may be the same or different, each represent an optionally substituted aryl or heterocyclic group; or R and R.sup.1 together with the tellurium atom therebetween represent a heterocyclic ring, which may contain one or more further heteroatoms, and which may carry substituents and/or fused aromatic rings.Type: GrantFiled: August 7, 1980Date of Patent: January 25, 1983Inventors: Derek H. R. Barton, Steven V. Ley, Clive A. Meerholz
