treatment with sulfur hexafluoride, alkali metal diphenyl or dicyclohexyl phosphides are oxidized within seconds to tetraphenyl or tetracyclohexyl diphosphines. When bulky di-tert-butylphosphide is employed, fluorophosphine intermediates are detected. This is the first reported reaction of sulfur hexafluoride with metal phosphides, and a rare example of reactivity of sulfur hexafluoride at ambient temperature

proposed to use the quantity ΔJ/JL(ΔJ=Jc–JL; Jc= P–F or P–H coupling constant of the co-ordinated ligand; JL= P–F or P–H coupling constant of the free ligand) as a measure of the π-donor strength of the metal carbonyl fragments, M(CO)x(M = Ni, x= 3; M = Cr, W, x= 5; or M = Mo, x= 3–5).
对双(叔丁基)氟膦,第一稳定的二烷基氟膦和相应的二氟膦的配体性质进行了评估。(CO)3 NiL,(CO)5 ML,顺式-(CO)4 MoL 2,顺式-(CO)3 MoL 3(L = Bu t PF 2和Bu t 2 PF; M = Cr,Mo,W)。使用ir和nmr数据(1 H,19 F,31 P),PF系列中膦的相对π受体特征3- Ñ卜吨Ñ( Ñ = O-3)进行了评估。它提出使用量Δ Ĵ / Ĵ大号(Δ Ĵ = Ĵ Ç - Ĵ大号; Ĵ Ç = P-F或P-H的协调配体的偶合常数; Ĵ大号= P-F或P-游离配体的H耦合常数)作为金属羰基片段的π-给体强度的量度,M(CO) x(M = Ni, x = 3; M = Cr,W, x = 5;或M = Mo, x = 3-5)。

Ligand maps lead to treasure! The activity of complexes of fluorophosphines (R2PF) in catalytic hydroformylation and hydrocyanation is predicted from a ligand map. However, the instability of R2PF to disproportionation is well‐documented. Examples of R2PF ligands (see scheme) are described that are stabilized to such an extent that they can be used in catalysis and are shown to be highly effective
