Efficient and Sustainable Electrosynthesis of -Sulfonyl Iminophosphoranes by the Dehydrogenative P-N Coupling Reaction.

Iminophosphoranes are commonly used reagents in organic synthesis and are, therefore, of great interest. An efficient and sustainable iodide-mediated electrochemical synthesis of -sulfonyl iminophosphoranes from readily available phosphines and sulfonamides is reported. This method features low amounts of supporting electrolytes, inexpensive electrode materials, a simple galvanostatic setup, and high conversion rates.
