Atom-economic synthesis of highly branched functional 'tripod-like' triphosphine sulfides

摘要

The tertiary polyfunctional triphosphine sulfides with amino and (or) ether groups have been synthesized in excellent yields by the exhaustive regioselective (in anti-Markovnikov manner) addition of secondary phosphines sulfides to trivinyl ethers of aminotriols and triols under free-radical conditions (UV-irradiation, 1.5-5 h).
