Procedure

To a solution of 78.4 L g (0.2 mole) bis(ethoxycarbonylethylene)tin dichloride in 160 ml toluene was added 15.6 g (0.2 mole) sodium sulfide as a 40% aqueous solution, while warming the mixture to maintain 85°-90° C. After the completion of the reaction, the layers were separated and the toluene solution of the product vacuum stripped to give the product as a viscous liquid, with refractive index 1.573 at 25° C. and infra-red absorption peaks at 1700, 1660, and 1190. The product analyzed 33.9% tin, (C2H5OCOCH2CH2)2SnS requires 33.7% Sn.
