Reaction of a tetraphenyl-1,2-diphosphinyl dianion with [FeCl2(THF)1.5] or [Ru(COD)(acac)2] yields dianionic complexes which further react with Ph3SnCl to afford the corresponding bis(1,4-diphosphabutadiene) complexes.
四苯基-1,2-
二膦酸二负离子与[FeCl2(THF)1.5]或[Ru(COD)(acac)2]反应生成二阴离子配合物,这些配合物进一步与Ph3SnCl反应,形成相应的双(1,4-
二膦丁二烯)配合物。
