Abstract
The invention comprises N-thiotrichloromethyl sultams of the formula <FORM:0783425/IV (a)/1> where R is a saturated aliphatic hydrocarbon radical of 3-6 C atoms, and a process for making them by the action of perchloromethylmercaptan on the alkali metal compound of an alkane sultam. An example is given of the preparation from a -methyl-g -propane sultam sodium salt of N-thiotrichloromethyl-a -methyl-g -propane sultam. The alkane sultams may be obtained by ring-closing the corresponding amino - alkane sulphochloride hydrochlorides with alkali, heating a chloroalkane sulphonamide, or by the action of ammonia on hydroxyalkane-sulphonic acids.
