An unprecedented atroposelective Catellani reaction between phosphine oxide-containing aryl bromides,aryliodides,and nucleophiles for the construction of phosphine-containing biaryl atropisomers was established using an enantiopure norbornene derivative as the chiral mediator.A broad range of atropisomeric biaryl-based monophosphine oxides were obtained in good efficiency with excellent enantioselectivity. 展开更多

The title complex,(μ-pdt)Fe_2(CO)_5(Ph_2PCH_3)(pdt = SCH_2CH_2CH_2S),was obtained by the reaction of the parent complex(μ-pdt)Fe_2(CO)_6 with Ph_2PCH_3 and Me_3NO·2H_2O in good yield(90%). The tit... The title complex,(μ-pdt)Fe_2(CO)_5(Ph_2PCH_3)(pdt = SCH_2CH_2CH_2S),was obtained by the reaction of the parent complex(μ-pdt)Fe_2(CO)_6 with Ph_2PCH_3 and Me_3NO·2H_2O in good yield(90%). The title complex was characterized by IR,~1H NMR,^(31)P{~1H} NMR and ^(13)C{~1H} NMR spectroscopy as well as by single-crystal X-ray diffraction analysis. The molecular structure shows that the title complex contains a butterfly diiron propanedithiolate cluster with five terminal carbonyls and a monophosphine ligand Ph_2PCH_3. The crystal packing diagram reveals that intermolecular C H···O hydrogen bonds between CH_2 and carbonyls,π-π stacking interactions and van der Waals' interactions stabilize the solid state to form a three-dimensional network. 展开更多
