= Ph, 1,1′-biphenyl-based, 1,1′-binaphthyl-based) efficiently. Traditional routes to these species, involving the use of chlorophosphites ClP(OR)2 were found to be ineffective. These “ferrophite” ligands have been characterised by X-ray crystallography (4 examples) and shown to be effective in both nickel-catalysed addition of AlMe3 to PhCHO (up to 77 % ee) and copper(I)-catalysed additions of organoaluminium
对映纯锂化 1,2-二茂铁,[CpFe1,2-η5-C5H3(Ar)(Li)}] (Ar = Ph, 4-CF3C6H4, 1-C10H7),容易与 PhOP(OR)2 反应生成[CpFe1,2-η5-C5H3(Ar)P(OR)2}](R = Ph,基于 1,1'-联苯,基于 1,1'-联萘)。发现这些物种的传统途径,包括使用氯亚磷酸酯 ClP(OR)2 是无效的。这些“铁磷矿”配体已通过 X 射线晶体学(4 个例子)进行表征,并且在镍催化的 AlMe3 添加到 PhCHO(高达 77% ee)和铜 (I) 催化的有机铝试剂添加中均显示有效到烯酮(高达 92% ee)。(© Wiley-VCH Verlag GmbH & Co.
