Process for the production of organic dithiopyrophosphates
摘要:
Organic dithiopyrophosphates of formula wherein R1, R2, R3, R4 and R5 independently are hydrogen, C1-4 alkyl, chloromethyl or bromomethyl, are prepared in a two-step process from the corresponding 1,3-diols and thiophosphoryl chloride, using 3-methylpyridine both as solvent and as base.
