The author of 《Photoinduced Transition-Metal-Free Cross-Coupling of Aryl Halides with H-Phosphonates》 were Zeng, Huiying; Dou, Qian; Li, Chao-Jun. And the article was published in Organic Letters in 2019. Formula: C7H7I The author mentioned the following in the article:
Preparation of arylphosphonates and phosphine oxides ArP(O)X2 (Ar = substituted Ph, naphthyl, biphenyl; X = OMe, OEt, OiPr, aryl) by photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar-Cl, Ar-Br, and Ar-I) with H-phosphonates (including dialkyl phosphonates and diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, Ph, trifluoromethyl, and heterocyclic compounds This simple and green strategy provides a practical pathway to synthesize arylphosphine oxides. The results came from multiple reactions, including the reaction of 1-Iodo-4-methylbenzene(cas: 624-31-7Formula: C7H7I)
1-Iodo-4-methylbenzene(cas: 624-31-7) is used in wide range of medicals industrial applications as well as in pharmaceutical intermediates, polarizing films for Liquid Crystal Display (LCD) chemicals.Formula: C7H7I
