various primary phosphine oxides of the general formula RP(H)2O (R = Mes*, MesTer, DipTer) and the molecular structure of DipTerP(O)H2 was determined. However, phosphanylidenephosphoranes are described to be highly nucleophilic as well. We show that the attachment of main group Lewis acids such as GaCl3 and GaI3 to R–P(PMe3) yielded the highly sensitive, yet stable coordination compounds [(RPGaX3)PMe3]
R-P(PR' 3 ) 型亚膦基正膦,也称为
磷-维蒂希试剂,可用于利用其膦类反应性的多种键活化反应。在此,我们彻底证明了用于 H 2 O 交换的简便 PMe 3可以得到通式为 RP(H) 2 O(R = Mes*、Mes Ter、Dip Ter)的各种初级氧化膦和Dip的分子结构测定了 TerP(O)H 2。然而,膦亚基正膦也被描述为高度亲核的。我们表明,GaCl 3和 GaI 3等主族
路易斯酸的附着对 R–P(PMe 3 ) 产生高度灵敏但稳定的配位化合物 [(R
PGaX 3 )PMe 3 ] (R = Mes*, Dip Ter) 或 [(RPPMe 3 ) 2 GaCl 2 ]GaCl 4 (R = Mes三)。与游离亚膦基正膦相比,这些物质与 H 2 O 的反应不同,这在 [(Mes*PPMe 3 )Gal 3 ] 中得到了证明。这里形成膦基
鏻阳离子 [Mes*P(H)PMe 3 ]
