Reaction of the ruthenium half sandwich compound RuCl(eta5- C5H5)(PPh3)2 with the uracil (Ur) substituted alkyne HCCUr in the presence of halide scavengers NH4X (X = PF6, BF4, OTf) results in the formation of the vinylidene complexes [Ru(CCHUr)(eta5-C5H 5)(PPh3)2][X] which crystallize in the hexagonal space group P6(3)/m. The hexagonal symmetry inherent to the system is due to the formation of a hydrogen bonded array mediated by the two sets of donor-acceptor units on the uracil, resulting in the formation of a cyclic “rosette” containing six ruthenium cations. In solution the 1H and 31P{1H} NMR spectra of the vinylidene complexes are both concentration and temperature dependent, in accord with the presence of monomer-dimer equilibria in which the rate of rotation of the vinylidene group is fast on the NMR timescale in the monomeric species, but slow in the dimers. The isoelectronic molybdenum-containing vinylidene complex [Mo(eta7-C7H7)(dppe)(CCHUr)][BF4] (dppe = 1,2-bis(diphenylphosphino)ethane) has also been prepared, but forms symmetric dimers in the solid state.

Ruthenium-assisted cyclizations of two enynes, HC?CCH(OH)(C 6H4)X-CH2CH=CMe2 (X=S (1 a), O (1 b)), each of which contains two terminal methyl substituents on the olefinic parts, are explored. The reaction of 1 a in CH2Cl2 gives the vinylidene complex 2 a from the first cyclization and two side products, 3 a and the carbene complex 4 a with a benzothiophene ligand. The same reaction in the presence of HBF4 affords 4 a exclusively. Air oxidation of 4 a in the presence of Et3N readily gives an aldehyde product. In MeOH, tandem cyclizations of 1 a generate a mixture of the benzothiochromene compound 10 a and the carbene complex 7 a also with a benzothiochromene ligand. First, cyclization of 1 b likewise proceeds in CH2Cl2 to give 2 b. Tandem cyclization of 1 b in MeOH yields comparable products 10 b and 7 b with benzochromene moieties, yet with no other side product. The reaction of [Ru]Cl with HC?CCH(OH)(C6H4)S-CH2CH= CH2 (1 c), which contains no methyl substituent in the olefinic part, in MeOH gives the carbene complex 15 c with an unsubstituted thiochromene by means of a C-S bond formation. Structures of 3 a and 15 c are confirmed by X-ray diffraction analysis. The presence of methyl groups of enynes 1 a and 1 b promotes sequential cyclization reactions that involve C-C bond formation through carbocationic species. Copyright

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), category: ruthenium-catalysts.

The reaction of 2-guanidinobenzimidazole (GBI) and (eta5-C5H5)Ru(PPh3)2(Cl) in refluxing toluene gives the chelate [(eta5-C5H5)Ru(PPh3)(GBI)]+Cl- (1+Cl-; 96%). Subsequent anion metatheses yield the BF4-, PF6-, and BArf- (B(3,5-C6H3(CF3)2)4-) salts (77-85%). Reactions with CO give the carbonyl complexes [(eta5-C5H5)Ru(CO)(GBI)]+X- (2+X-; X- = Cl-, BF4-, PF6-, BArf-; 87-92%). The last three salts can also be obtained by anion metatheses of 2+Cl- (77-87%), as can one with the chiral enantiopure anion P(o-C6Cl4O2)3- ((delta)-TRISPHAT-; 81%). The reaction of [(eta5-C5H5)Ru(CO)(NCCH3)2]+PF6- and GBI also gives 2+PF6- (81%). The pentamethylcyclopentadienyl analogues [(eta5-C5Me5)Ru(CO)(GBI)]+X- (3+X-; X- = Cl-, BF4-, PF6-, BArf-; 61-84%) are prepared from (eta5-C5Me5)Ru(PPh3)2(Cl), GBI, and CO followed (for the last three) by anion metatheses. An indenyl complex [(eta5-C9H7)Ru(PPh3)(GBI)]+Cl- (96%) is prepared from (eta5-C9H7)Ru(PPh3)2(Cl) and GBI. All complexes are characterized by NMR (1H, 13C, 31P, 19F, 11B), with 2D spectra aiding assignments. Crystal structures of 1+PF6-·CH2Cl2 and 1+BArf-·CH2Cl2 are determined; the anion is hydrogen bonded to the cation in the former. Complexes 1-3+X- are evaluated as catalysts (10 mol %, RT) for condensations of indoles and trans-beta-nitrostyrene. The chloride salts are ineffective (0-5% yields, 48-60 h), but the BArf- salts exhibit excellent reactivities (97-46% yields, 1-48 h), with the BF4- and PF6- salts intermediate. Evidence for hydrogen bonding of the nitro group to the GBI ligand is presented. GBI shows no catalytic activity; a BArf- salt of methylated GBI is active, but much less so than 2-3+BArf-.
