  The complex Ru(CO)(CH = CHPh)Cl(C5,H5N)(PPh3)2 and related alkenyl complexes react in methanol or ethanol to give (E,E)-1,4-diphenylbuta-1,3-diene and the ruthenium(II) hydride Ru(CO)H(Cl)(C5H5N)(PPh3)3. Further reaction of this hydride with the butadiene results in 1,2-reduction to yield (E)-1,4-diphenyl-1-butene. However, the reaction of phenylacetylene with catalytic amounts of ruthenium hydrides gave the dimer (Z)-1,4-diphenylbuten-3-yne. On the other hand, the reaction of 1,2-diphenylethenylruthenium(II) derivatives in methanol or ethanol gave trans-stilbene rather than the butadiene. Several deuteriation experiments were performed in order to elucidate the mechanism of formation of (E, E)-1,4-diphenylbuta-1,3-diene and ruthenium hydride from the corresponding alkenyl complexes.

  Neutral ruthenium hydrides Ru(CO)ClH(L)(PPh3)(2) bearing one N-donor ligand react with 1-alkynes at 23 degrees C to yield neutral alkenyl complexes Ru(CO)Cl(CH=CHR)(L)(PPh3)(2). Under similar conditions, cationic hydride complexes [Ru(CO)H(L)(2)(PPh3)(2)]PF6 with pyridine-type N-donor ligands yield alkynyl complexes [Ru(CO)(CH=CHR)(L)(2)(PPh3)(2)]PF6 as a result of the reaction of the intermediate labile alkenyl with a second molecule of alkyne, Under more forcing conditions, 1-alkynyl complexes could also be prepared from the neutral ruthenium hydrides. Cationic ruthenium hydrides with bidentate N-donor ligands are unreactive toward 1-alkynes, Neutral alkenyl complexes Ru(CO)Cl(CH=CHR)(L)(PPh3)(2) (R = p-MeC6H4, CMe3; L = pyridine, isoquinoline) reacted smoothly with 1-alkynes to afford the corresponding sigma-alkynyl ruthenium derivatives Ru(CO)Cl(C=CR)(L)(PPh3)(2).

  The reaction Of Ru(CO)ClH(PPh3)3 with 1-alkynes in 1,2-dichloroethane under reflux conditions provides the coordinatively unsaturated butenynyl complexes [RuC(C=CR)=CHR}(CO)Cl(PPh3)2] in good yield. These and related butenynyl complexes were also prepared by starting from the corresponding alkenyl- or alkynylruthenium complexes. Hydrogenolysis of [RuC(C=CPh)=CHPh}(CO)Cl(PPh3)2] in the presence of pyridine gave (Z)-1,4-diphenylbutenyne and Ru(CO)ClH(py)(PPh3)2.

  Substitution of one or two triphenylphosphine ligands of Ru(CO)ClH(PPh(3))(3) by bidentate diphosphines Ph(2)P(CH2)(n)PPh(2) (L-L) (n = 1, dppm; n = 2, dppe; n = 3, dppp; n = 4, dppb) or 1, 1'-bis(diphenylphosphino)ferrocene (dppf) led to hydrides Ru(CO)ClH(PPh(3))(2)(L-L) or Ru(CO)ClH(PPh(3))(L-L). The hydride complexes were characterized spectroscopically and by one X-ray structure. Hydride Ru(CO)ClH(PPh(3))(dppf) crystallizes in the monoclinic space group P2(1)/n, with a 17.768(1) Angstrom, b = 25.252(2) Angstrom, c 11.213(1) Angstrom, beta = 92.83(1)degrees, Z = 4, and V = 4459.3(6) Angstrom(3). Reaction of Ru(CO)ClH(PPh(3))(3) or [Ru(CO)H(MeCN)(2)(PPh(3))(2)](PF6-)-P-+ with 2 equiv of diphosphines L-L led to [Ru(CO)H(L-L)(2)](+)A(-) (L-L = dppm, dppe, dppp) (A = Cl, PF6). Hydrides Ru(CO)ClH(PPh(3))(2)(L-L) react with 1-alkynes to give alkenyl complexes Ru(CO)Cl(CH=CHR)(PPh(3))(L-L) with a chelating diphosphine ligand. Ru(CO)ClH(PPh(3))(L-L) gave sigma-alkynyl complexes Ru(CO)Cl(C drop CR)L(L-L) directly in their reactions with 1-alkynes. The hydride with dppb as the ligand showed the highest reactivity. The preparation of hexaco ordinated alkenyl derivatives Ru(CO)Cl(CH=CHR)(PPh(3))(L-L) with a chelating diphosphine was carried out by treatment of other alkenyl derivatives with the diphosphines. Surprisingly, reaction of alkenyls Ru(CO)Cl(CH=CHR)(Me(2)Hpz)(PPh(3))(2) (R = CMe(3), p-MeC(6)H(4)) with dppf led to complexes Ru(CO)Cl(CH=CHR)(Me(2)Hpz)(dppf) by substitution of both PPh(3) ligands instead of the dimethylpyrazole. Ruthenium alkenyls Ru(CO)Cl(CH=CHR)L(dppf) (L = Me(2)Hpz, PPh(3)) react cleanly with 1-alkynes at room temperature to give alkynyl complexes Ru(CO)Cl(C drop CR)L(dppf) in good yield. This reaction was applied to the synthesis of a bimetallic complex Ru(CO)Cl(PPh(3))(dppf)(C drop C-p-C6H4C drop C)Ru(CO)Cl(PPh)(dppf) as a mixture of meso and dl diastereomers.
