Mixed phosphine-arsine ligands

Excess phosphine does not induce further substitution of CO in IV, except when the allyl moiety consists of a cyclohexenyl group. However, bidentate ligands, e.g., diphosphines - , diarsines and mixed phosphine-arsines displace two CO molecules ... [Pg.170]

Rather than utilizing complete transmetallation reactions, mixed metal silver(i) aryl complexes 8-11 were obtained from the reaction of soluble silver salts with arylgold(i) complexes possessing ancillary phosphine or arsine ligands, as shown in Scheme l.29,30... [Pg.200]

Mixed phosphine-fluorophosphine (160, 247, 164, 173, 174), phos-phite-fluorophosphine (174), tertiary amine-fluorophosphine (174), carbonyl-fluorophosphine (160, 173, 56, 58, 59), tertiary arsine-fluoro-phosphine (174,175), and stibine-fluorophosphine complexes are readily formed directly from the appropriate fluorophosphine-metal complex. Only in the case of carbon monoxide, chlorophosphines, and phosphites is it possible to completely displace all the fluorophosphine ligands from the metal. Some typical examples are quoted below ... [Pg.429]

The diarsine and arsine/phosphine analogues of dppm have been used to prepare bridged diplatinum(I) complexes, in both cases with terminal chloro ligands.116,117 Both complexes react with carbon monoxide to produce carbonyl-bridged species. The mixed thio/phosphine ligand Ph2PCH2SMe (PS) also forms a diplatinum(I) complex by conproportionation of its dichloroplat-inum(II) complex with [Pt(dba)2].118 This dimer reacts with carbon monoxide to produce an unsupported dimer [PtCl(PS)(CO)]2 with the thioether arm of the Ph2PCH2SMe unbound. [Pg.687]

Complexes with mixed C,P or C,As donor ligands are derived of ortho-metalated phosphines or arsines or of methanide derivatives. The dinuclear complexes [Au2(C6F[3-2-EPh2-6-R)2] (E = P (589), As R = H, Me) are obtained by reaction of 2-EPh2-6-R-C6F[3Li with [AuBr(PEt3)] at —70 °c.2002 2004,20 6 The treatment of the dimer [Au2(C6Fl4PPh2)2] with methyltriflate yields, unexpectedly, [Au5(C6Fl4PPh2)4]+.3134 The mixed dinuclear derivative [Au2(5-Me-C6H3-2-... [Pg.1076]
