1,2-Bis(dichlorophosphino)benzene is an organophosphorus compound with the formula C6H4(PCl2)2. This viscous colorless liquid is a precursor to chelating diphosphines of the type C6H4(PR2)2. [1] It is prepared from 1,2-dibromobenzene by sequential lithiation followed by treatment with (Et2N)2PCl (Et = ethyl), which affords C6H4[P(NEt2)22. This species is finally cleaved with hydrogen chloride: [2]
