There is disclosed a process for the preparation of sulfenimides comprising: mixing, in a hydrocarbon solvent, a sulfenamide of the formulawith an aldehyde of the formulawhere X is a sulfur atom, a -C=N- group, or a -C=C- group, R1 and R2 are independently selected from the group consisting of hydrogen, alkyl, and aryl or may be joined to form a saturated or unsaturated ring or aromatic ring, R3 is alkyl or cycloalkyl, and R4 is a hydrocarbon radical wherein the carbon bearing the aldehyde function is bonded only to other carbon atoms, a substituted or unsubstituted aryl ring, or a heteroaromatic ring; and heating the mixture at a temperature and for a period of time sufficient to convert the sulfenamide to the sulfenimide.
