Thiolane 1,1-dioxide was prepd. by catalytic hydrogenation of a cyclic sulfone deriv. with H in the presence of a catalyst of Pd sulfide on Al2O3 at 85-100° and elevated H pressure. The process is simplified and the product yield increased by using as the cyclic sulfone deriv. 3-alkoxythiolane 1,1-dioxide I (R = C4-12 alkyl), and carrying out the process in aq. alk. soln. at a H pressure of 45-50 atm.
