Synthesis of\nSulfenamides via Photoredox N–S\nCoupling of Dialkyl Azodicarboxylates and Thiols

We herein report a photoredox N–S coupling reaction\nbetween\ndialkyl azodicarboxylates and thiols to access sulfenamide scaffolds.\nThis reaction proceeds under mild, green, and operationally simple\nconditions, offering a broad scope of sulfenamides with high yields\nand excellent atom efficiency. Mechanistic investigations revealed\nthis reaction followed a photoinitiated radical pathway in which iodide\nplays a crucial role as both a radical initiator and a single-electron\nreductant.
