摘要

The sulfurization efficiency of 25 3-substituted-1, 2, 4-dithiazole-5-ones and 5-thiones towards triphenyl phosphite in acetonitrile, DCM, THF and toluene at 25° C was evaluated. All the 1, 2, 4-dithiazoles are much better sulfurizing reagents than commercially available agents (PADS, TETD, Beaucage's reagent). The most efficient sulfurizing agents in all solvents are 3-phenoxy (4), 3-phenylthio (5) and 3-ethoxy-1, 2, 4-dithiazole-5-one (1) ...
