Process for the sulfurisation of phosphorus-containing compounds

摘要

The invention relates to a process for the sulfurization of phosphorus-containing compounds which comprises contacting the phosphorus compound to be sulfurized with a sulfur transfer reagent of formula (I) wherein R<1> is aryl which can be substituted by halogene, (C1 - C6) alkyl, (C1 - C6) alkoxy R<2> is (C1 - C6) alkyl, which could also form a cycle together with R<1>
