A new aerobic oxidative coupling of thiols in water to construct sulfenamides or disulfides was developed, utilizing cobalt(II)phthalocyanine-tetra-sodium sulfonate as the catalyst and O2 as the oxidant. The mother liquor could be recycled up to 20 times with negligible loss of activity and only a minor decrease of product yield.
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.
