2-carboxyethylthio phenyl

Carboxyethylthio Phenyl Tellurium4 A solution of 1.06 g (10 mmol) of 2-carboxyethanethiol in 25 ml of ethanol is added to a solution of 2.05 g (5 mmol) of diphenyl ditellurium in 175 ml of ethanol. The resultant mixture is stirred at 20° for 24 h and then concentrated to a volume of 50 ml. Water is added to the concentrate until the mixture becomes cloudly and the mixture is cooled overnight. The precipitated solid is collected and dried yield 1.1 g (35%) m.p. 40°.
