Abstract
Abstract Enantiomerically pure ethylmethylphenyltelluronium salts were isolated by optical resolution from a diastereomeric mixture of ethylmethylphenyltelluronium (1S)-(+)-camphor-10-sulfonate and subsequent anion exchange reactions, and the absolute configurations were determined based on the X-ray crystallographic analysis of a diastereomeric isomer.
