摘要

2, 2, 6, 6-Tetramethylpiperidine-1-oxyl (TEMPO), upon reaction with thiophenols, undergoes deoxygenation leading mainly to the formation of tetramethylpiperidinium arylsulphinates and arylsulphonates. Other identified products of the reaction are aryldisulphides, 2, 2, 6, 6- tetramethylpiperidine, S-arylarylthiosulphonates, N-arylsulphinyl-and N-arylsulphonyl-2, 2, 6, 6-tetramethyIpiperidine. The formation of the reaction products is discussed on the ...
