摘要:
.alpha.-Oxothiodimethylamide compounds such as tert.-butyl-glyoxyl acid thiodimethylamide are prepared by reacting an .alpha.-chloroketone of the formula ##STR1## in which X is hydrogen or chlorine andR.sup.1 is alkyl or arylWith sulfur and dimethylamine in water at a temperature between 50.degree. and 90.degree. to produce the corresponding .alpha.-oxothiodimethylamide of the formula ##STR2## wherein R.sup.1 is identified above.
