Abstract

Sulfurization of β-dithiolactone (4) gave corresponding 1, 2-dithiolane-3-thione (2a) via an ionic intermediate. Oxidation of β-dithiolactone 4 by m-CPBA afforded corresponding S- oxide (11), while dioxide (12) was obtained when 3equiv of m-CPBA was used. Dithiolane-3- thione 2a reacted with ethylenebis (triphenylphosphine) platinum or tetrakis (triphenylphosphine) palladium to afford the corresponding dithiolato-platinum (20) and ...
