X-Ray crystal structure of 2,4,6-tris(p-methoxyphenyl)-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trisulphide, a co-product in PO → PS thionation with Lawesson's reagent
Abstract
2,4,6-Tris(p-methoxyphenyl)-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trisulphide 2, obtained from trimethyl phosphonoformate ester 3 and Lawesson's reagent 1 in acetonitrile, has been structurally characterized by X-ray diffraction.
