The new method, which gives all primary and secondary thiols from the corresponding carbonyl compounds with high selectivity, involves the action of hydrogen sulfide on the carbonyl in the presence of a thiol, preferably mathanethiol, acting as a reductant. The thiol yield is optimal at 200/sup 0/-300/sup 0/C over about 5Vertical Bar3< potassium on alumina and at a hydrogen sulfide/carbonyl mole ratio above 5:1 and a reductant thiol/carbonyl mole ratio above 3:1. The conversion of pinacolone to 3,3-dimethyl-2-butanethiol exemplifies the method. The initial cost is high, but competitiveness with classical industrial methods is possible.
