A new method converting thioamides to ketene S,S-acetals, which exhibits wide compatibility with olefin, ketone, ester and amide groups, has been described. Thioamides have proved to be synthetically very potential by the total synthesis of Vitamin Bl2 (construction of corrin molecule) by Woodward a

The cathodic reduction of ketene S,S-acetals in aprotic media has been investigated. Because of instability of the radical anion the reduction steps are irreversible. In prcsenec of carbon dioxide the half-wave potentials are shifted to more positive values and preparative scale electrolysis yields
