Treatment of [(eta5-C5R5)Ru(L)2]BF4 (R = Me, (L)2 = dppe; R = H, (L)2 = (PPh3)2) with 0.45 equiv of HC?CCH(OH)C?CH led to the formation of the C5H2-bridged compounds [(eta5-C5R5)(L) 2Ru=C=C=CHCH=C=Ru(L)2(eta5-C 5R5)](BF4)2. The C5H2-bridged compounds reacted with alumina to give the C5H-bridged compounds [(eta5-C5R5)(L) 2Ru=C=C=CHC=CRu(L)2-(eta5-C5R 5)]BF4. The structure of the C5H-bridged complex [Cp(PPh3)2Ru=C=C=CHC=CRu-(PPh3) 2Cp]BPh4 has been confirmed by X-ray diffraction and shows the bridging C5H ligand to be symmetric with a delocalized pi-system. Reaction of [(eta5-C5R5)(L) 2Ru=C=C=CHC=CRu-(L)2(eta5-C5R 5)]BF4 with acetone in the presence of KOH or KOBut produced (eta5-C5R5)(L)2-RuC=CCH(CH 2COMe)C=CRu(L)2(eta5-C5R 5).

The coordination chemistry of bisphosphine ligands assembled on the five-membered heterocyclic platform of bis(azol-1-yl)methane viz.: bis(2-diphenylphosphinoimidazol-1-yl)methane (1), bis(5-diphenylphosphinopyrazol-1-yl)methane (2) and bis(5-diphenylphosphino-1,2,4-triazol-1-yl)methane (3) with RuII, RhI, PdII and PtII is described. The bisphosphines 1-3 react with elemental selenium to give the corresponding bis-selenoyl derivatives 4-6. The reactions of 1-3 with transition metal derivatives produce complexes with different coordination modes. Bisphosphine 1 showed a preference for the kappa2-P,P mode of coordination, whereas bisphosphines 2 and 3, besides the kappa2-P,P mode also showed a head-to-tail kappa2-P,N coordination mode resulting in the formation of binuclear complexes [Rh2(COD)2{(CH2(1,2-C3H2N2PPh2)2)-kappa2P,N}][BF4]2 (14), [Rh2(COD)2{(CH2(1,2,4-C2HN3PPh2)2)-kappa2P,N}][BF4]2 (15), [Pd2(eta3-C3H5)2{(CH2(1,2-C3H2N2PPh2)2)-kappa2P,N}][BF4]2 (21) and [Pd2(eta3-C3H5)2{(CH2(1,2,4-C2HN3PPh2)2)-kappa2P,N}][BF4]2 (22). Several of these complexes have also been structurally characterized. The in situ generated RhI complex of bisphosphine 1 showed moderate to good selectivity in the hydroformylation of various styrene derivatives.

The reaction between CF3CN and (RuCl(PPh3)2(eta-C5H5)) affords (RuNH=C(CF3)N=C(CF3)NH(PPh3)(eta-C5H5)); exchange with P(OMe)3 gives the corresponding trimethyl phosphite complex, whose structure has been determined by X-ray diffraction methods.The complex contains a planar metallocycle in which the ruthenium atom is bonded on both sides to NH, then through C(CF3) to a lone nitrogen atom.The co-ordination around the metal atom is octahedral (with C5H5 occupying three sites) and the orthogonality is preserved despite the requirements of the ring geometry.The bonds within the ring are delocalised to give effective mirror symmetry across the Ru…N vector, with mean bond lengths: Ru-NH, 2.078(5); HN-C(CF3), 1.287(8); (CF3)C-N, 1.339(9); and C-CF3, 1.514(11) Angstroem.The angles at N(H) and C(CF3) adjust to accommodate these rather varied bond lengths, but the angle at the unique N atom remains 120 degree.Within the cyclopentadienyl ring the Ru-C distances vary between 2.15 and 2.27 Angstroem, the longer ones being trans to the Ru-P bond.

The gold acetylide complex 20 endowed with a biaryl backbone provides opportunities for a study on the formation and fate of gold vinylidenes. Although the formyl group in 20 is not sufficiently electrophilic to get attacked by the acetylide in proximity, its activation with TBSOTf (TBSOTf=tert-butyldimethylsilyl trifluoromethanesulfonate) at low temperature triggered instantaneous formation of a gold vinylidene (21). This metastable species evolved into the cationic gold carbene complex 22 bearing a phenanthrene unit and a hydroxyl group at the aurated center; the recorded data suggest that this product might be better viewed as an acylgold species protonated by triflic acid. The use of [Me3O?BF4] as the activating agent led to formation of the analogous Fischer-type carbene 24, whereas replacement of gold by the [CpRu(PPh3)2]+ fragment allowed the ruthenium vinylidene 27 to be isolated, which closely resembles the proposed gold intermediate 21. The starting gold complex 20, the derived products 22 and 24, as well as vinylidene 27 were characterized by X-ray diffraction.

A new ferrocenyl-bisphosphine, 1,1?-bis(dipyrrolylphosphino)ferrocene (dpypf) (1) was synthesized by the reaction of [Fe(C5H4PCl2)2] with lithiated pyrrole at ?78 C. The bis(selenide) [Fe{C5H4P(Se)(NC4H4)2}2] (2) and tetracarbonyl derivatives [M(CO)4(dpypf)] (3, M = Mo; 4, M = W) were synthesized by reacting 1 with elemental selenium and [M(C5H11N)2(CO)4] (M = Mo, W), respectively. The reaction of 1 with [Ru(eta6-p-cymene)Cl2]2in 1:2 molar ratio yielded the dinuclear complex [{Ru(eta6-p-cymene)Cl2}2(mu-dpypf)] (5), whereas the reaction with [CpRu(PPh3)2Cl] in 1:1 molar ratio produced a chelate complex [CpRuCl(dpypf)] (6). The reactions of 1 with M(COD)Cl2(M = Pd, Pt) yielded chelate complexes, [MCl2(dpypf)] (7, M = Pd, 8, M = Pt). Treatment of 1 with AgOTf in 1:1 molar ratio gave a dinuclear complex [Ag(mu-OTf)(dpypf)]2(9). Gold complex [Au2Cl2(mu-dpypf)] (10) was obtained by reacting 1 with two equivalents of [AuCl(SMe2)]. Crystal structures of 2?4 and 6?10 were established by single-crystal X-ray diffraction studies.

This work reports a novel method for the direct aminophosphonylation of aldehydes catalyzed by cyclopentadienyl ruthenium(II) complexes. The system HP(O)(OEt)2/[CpRu(PPh3)2Cl] was very efficient for the aminophosphonylation of aldehydes with primary and secondary amines, producing the corresponding alpha-aminophosphonates in good to excellent yields. This novel method has several advantages including the use of a small amount of catalyst (0.5 mol%), high chemoselectivity, solvent-free conditions and application of the catalyst [CpRu(PPh3)2Cl] for at least 12 cycles with excellent activity.

Transition metal alkynyl complexes containing perfluoroaryl groups have been prepared directly from trimethylsilyl-protected mono- and di-ethynyl perfluoroarenes by simple desilylation/metallation reaction sequences. Reactions between Me3SiCCC6F5 and RuCl(dppe)Cp? [Cp? = Cp, Cp*] in the presence of KF in MeOH give the monoruthenium complexes Ru(CCC6F5)(dppe)Cp? [Cp? = Cp (2); Cp* (3)], which are related to the known compound Ru(CCC6F 5)(PPh3)2Cp (1). Treatment of Me 3SiCCC6F5 with Pt2(mu-dppm) 2Cl2 in the presence of NaOMe in MeOH gave the bis(alkynyl) complex Pt2(mu-dppm)2(CCC6F 5)2 (4). The Pd(0)/Cu(i)-catalysed reactions between Au(CCC6F5)(PPh3) and Mo(?CBr)(CO) 2Tp* [Tp* = hydridotris(3.5-dimethylpyrazoyl)borate], Co3(mu3-CBr)(mu-dppm)(CO)7 or ICCFc [Fc = (eta5-C5H4)FeCp] afford Mo(?CCCC 6F5)(CO)2Tp* (5), Co3(mu 3-CCCC6F5)(mu-dppm)(CO)7 (6) and FcCCCCC6F5 (7), respectively. The diruthenium complexes 1,4-{Cp?(PP)RuCC}2C6F4 [(PP)Cp? = (PPh3)2Cp (8); (dppe)Cp (9); (dppe)Cp* (10)] are prepared from 1,4-(Me3SiCC)2C6F4 in a manner similar to that described for the monoruthenium complexes 1-3. The non-fluorinated complexes 1,4-{Cp?(PP)RuCC}2C6H 4 [(PP)Cp? = (PPh3)2Cp (11); (dppe)Cp (12); (dppe)Cp* (13)], prepared for comparison, are obtained from 1,4-(Me3SiCC)2C6H4. Spectro-electrochemical studies of the ruthenium aryl and arylene alkynyl complexes 2-3 and 8-13, together with DFT-based computational studies on suitable model systems, indicate that perfluorination of the aromatic ring has little effect on the electronic structures of these compounds, and that the frontier orbitals have appreciable diethynylphenylene character. Molecular structure determinations are reported for the fluoroaromatic complexes 1, 2, 3, 6 and 10.
