A family of hydride complexes of rhodium. Crystal structure of the paramagnetic rhodium(III)–rhodium(II) complex [(triphos)Rh(µ-H)3Rh(triphos)](BPh4)2·DMF [triphos = MeC(CH2PPh2)3, DMF = dimethylformamide]
A family of hydride complexes of rhodium. Crystal structure of the paramagnetic rhodium(III)–rhodium(II) complex [(triphos)Rh(µ-H)3Rh(triphos)](BPh4)2·DMF [triphos = MeC(CH2PPh2)3, DMF = dimethylformamide]
The (triphos)Rh fragment [triphos = MeC(CH2PPh2)3] is able to form strong bonds with several reactive species (hydride, alkyl, carbon monoxide, alkenes), some reactions of which are highly specific; preliminary results on the hydrogenation and hydroformylation of hex-1-ene using (triphos)RhH(C2H4) as catalyst precursor are discussed.
(triphos)Rh片段[triphos = MeC(CH 2 PPh 2)3 ]能够与几种反应性物种(氢化物,烷基,一氧化碳,烯烃)形成强键,其某些反应具有高度特异性;讨论了以(triphos)RhH(C 2 H 4)为催化剂前体对己-1-烯进行氢化和加氢甲酰化的初步结果。

The rhodium alkyl and aryl complexes [(tri-phos)Rh(R)(eta(2)-C2H4)] (R = Me (1), Et (2), Ph (3); tri-phos = MeC(CH2PPh2)(3)) react with white phosphorus in THF at room temperature to give the new complexes [(triphos)Rh(eta(1):eta(2)-P4R)] (R = Me (4), Et (5), Ph (6)). This reaction represents the first example in which a P-C bond is formed by starting from white phosphorus through the mediation of a transition-metal complex.
