Abstract

The oxidation of 1-unsubstituted or 1-phenyl-1H-isotellurochromenes with m-chloroperbenzoic acid (mCPBA) in CHCl3 resulted in a ring opening reaction to produce as the sole products the corresponding o-formyl or benzoyl distyryl ditellurides, which were also produced by the hydrolysis of the 2-benzotelluropyrylium salts readily prepared from the parent isotellurochromene.
Keywords: isotellurochromene; mCPBA oxidation; 2-benzotelluropyrylium salt; distyryl ditelluride isotellurochromene; mCPBA oxidation; 2-benzotelluropyrylium salt; distyryl ditelluride
