Patent ID: 7291741

Claim:
A method for the production of N-alkyl-2-benzthiazolyl-sulfeneimides of the formula I where R is selected from the group consisting of a C 1 to C 12 unbranched or branched alkyl and a C 3 to C 9 cycloalkyl group, the method comprising reacting a 2-benzthiazolylsulfenyl chloride with an excess of a corresponding alkylamine in an inert solvent reaction medium, wherein the reaction of the sulfenyl chloride with the corresponding alkylamine is performed at a temperature of from +5 to +15° C. using a 10 to 100% excess of the alkylamine compared with a theoretical amount, removing moisture of equipment, solvent, and raw material by distilling off a part of the solvent by azeotropic distillation at an atmospheric or reduced pressure, and removing disulfide which has not reacted by adding aqueous sodium hydroxide at a temperature of 20 to 50° C., while separating the sulfeneimide by filtration.
