Yp. Luo et al., A convenient synthesis of derivatives of 1,3,2-dioxaphosphocane-2-sulfide with bioacitivity via Lawesson's reagent, HETEROCYC C, 7(1), 2001, pp. 37-41
Lawesson's reagent, 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,
4-disufide, reacted with the substituted 1,5-bisphenol L to afford derivati
ves of 1,3,2-dioxaphosphocane-2-sulfide 2, which were found to possess sele
ctive herbicidal activity against rape.
