Zuo, Ziqing;Kim, Raphael S.;Watson, Donald A. research published 《 Synthesis of Axially Chiral 2,2′-Bisphosphobiarenes via a Nickel-Catalyzed Asymmetric Ullmann Coupling: General Access to Privileged Chiral Ligands without Optical Resolution》, the research content is summarized as follows. The authors report an asym. homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched biaryl bisphosphines without need for chiral auxiliaries or optical resolution This provides a practical route for the development of previously unstudied atroposelective biaryl bisphosphine ligands. The conditions also proved effective for asym. dimerization of other, nonphosphorus-containing aryl halides.

1-Bromo-3,5-dimethoxybenzene (1BDMB) is a synthetic molecule that can be used as an electron acceptor in organic photovoltaic cells. 1BDMB is a salt of the sodium salt of resorcylic acid and 1,3-dibromo-5,5-dimethoxybenzene. It has been shown to have a radical mechanism for the generation of free radicals. The radical mechanism is initiated by light absorption by the ruthenium complex at the center of the molecule which induces photoinduced electron transfer from the ruthenium to 1BDMB. This process results in electron transfer from the donor to an acceptor molecule, such as oxygen or nitrogen. The pharmacokinetic properties of this compound are not well known; however, it has been demonstrated that it can be synthesized through a cross-coupling reaction with other aromatic compounds such as stemofuran., 20469-65-2.
