New methods of syntheses of silyl derivatives of phosphorus(V) thioacids on the basis of tetraphosphorus decasulfide, 1,3,2,4-dithiadiphosphetane-2,4-disulfides, and bis(trimethylsilyl)acetamide
Abstract
Mixed O,S-bis- and tris(trimethylsilyl) esters of dithiophosphoric, aryldithiophosphonic and trithiophosphoric acids, 3, 7a–c, and 9, respectively, were obtained by the reactions of tetraphosphorus decasulfide 1 and 1,3,2,4-dithiadiphosphetane-2,4-disulfides 6a–c and 8 with bis(trimethylsilyl)acetamide 2. © 2000 John Wiley & Sons, Inc.
