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)2.10.1021/ja103973a 20681696 Iron-Catalyzed Suzuki−Miyaura Coupling of Alkyl Halides Journal of the American Chemical Society 132 31 10674–10676 2010 Hatakeyama Takuji Hashimoto Toru Kondo Yoshiyuki Fujiwara Yuichi Seike Hirofumi Takaya Hikaru Tamada Yoshinori Ono Teruo Nakamura Masaharu
It is prepared from 1,2-dibromobenzene by sequential lithiation followed by treatment with (Et2N)2PCl (Et = ethyl), which affords C6H4[P(NEt2)2]2. This species is finally cleaved with hydrogen chloride:10.1021/ol010219y 11735590 BINOL-Based Diphosphonites as Ligands in the Asymmetric Rh-Catalyzed Conjugate Addition of Arylboronic Acids Organic Letters 3 25 4083–4085 2001 Reetz Manfred T.
