An iodine-mediated sulfenamides synthesis was reported. By using iodine as oxidant, various heterocyclic thiols and amines (mainly secondary amines) could smoothly proceed the CDC reaction, affording the target N−S formation products with good yields. The protocol features metal-free, easy performance, and short reaction time.
This invention relates to an improved process for preparing thiazolesulfenamides from aqueous chloramines and alkali metal salts of mercaptothiazoles, in water. The chloramine mixture can be prepared from amines or aqueous amine salt solutions.
