Cross metathesis between silylalkynes and various functionalized alkenes catalyzed by Grubbs carbene complex produced, in most cases, single regio- and stereoisomers of the resultant 1,3-dienes. Polar heteroatom substituents at the propargylic site are important for high reactivity and selectivity. An important mechanistic insight regarding the initiation event and the key propagating alkylidene in this reaction was obtained by employing a tandem cross metathesis ring-closing metathesis between a terminal alkene and a silylated alkyne possessing an alkene tether.

The Ru-N bond distances in the title complex, [Ru(NO2)(C11H9N3)(C15 H11N3)]BF4 or [Ru(NO2)(tpy)(azpy)]-BF4, [tpy is 2,2?:6?,2?-terpyridine and azpy is 2-(phenylazo)-pyridine], are Ru-Npy 2.063 (4), Ru-Nazo 2.036 (4), Ru-Nnitro 2.066 (3) A, and Ru-Ntpy 2.082(4), 1.982 (3) and 2.074 (4) A. The azo N atom is trans to the nitro group. The azo N=N bond length is 1.265 (5) A, which is the shortest found in such complexes to date. This indicates a multiple bond between Ru and the N atom of the nitro group, and pi-backbonding [dpi(Ru) ? pi*(azo)] is decreased.

Abstract Series of mononuclear complexes of arene Ru and Cp?Rh/Cp?Ir complexes containing (3-picolyl)thiourea derivative ligands, of general formulae [(eta6-arene)Ru(L)Cl]Cl and [Cp?M(L)Cl]Cl {L = benzoyl(3-picoylyl)thiourea, arene = benzene (1); p-cymene (2) and M = Rh (3); Ir (4); L = 1,3-bis(3-picolyl)thiourea, arene = benzene (5); p-cymene (6) and M = Rh (7); Ir (8)}, have been synthesized and characterized by spectroscopic methods. X-ray crystallographic studies of complexes (2)-(5), (7), and (8) reveal a typical piano-stool geometry around the metal center with a six-membered metallacycle, in which L acts as an N,S-chelating ligand. Intramolecular N-H¡¤¡¤¡¤S, S¡¤¡¤¡¤O, and N-H¡¤¡¤¡¤N interactions are found to play a significant role in the molecular structures.

The reaction velocity follows first-order kinetics with respect to the organic substrate at its lower concentrations and tends to become zero order at higher concentrations in the presence of ruthenium(III). The reaction follows first-order kinetics with respect to ruthenium(III) chloride. On the other hand, the rate of the reaction is directly proportional to the lower concentrations of ruthenium(VIII), but at higher catalyst concentrations the calalytic behavior is decreased. The reaction rate shows direct proportionality with respect to the organic substrate in the presence of ruthenium(VIII).

An efficient hydrogen bonding-guided ring-closing metathesis (RCM) reaction of sterically demanding homoallyl 2-(hydroxymethyl)acrylates catalyzed by the Hoveyda-Grubbs 2nd generation catalyst was developed and the reaction mechanism was explored. Adding a substituent to the hydroxymethyl group in this scaffold resulted in a class of challenging RCM substrates, although usable yields could be obtained. However, substrates bearing a 1-oxygenated alkyl group on the homoallylic carbon gave excellent RCM yields, providing a practical solution. Experimental and computational evidence indicated an unusual directing effect of OH?Cl hydrogen bonding between the substrate and Ru catalyst, which guides Ru to interact with the electron-deficient, more hindered acrylic C=C bond and thus triggers the RCM process.

The reaction of equal mole each of [Ni(L1)], [Ni(L2?Me)], [Ni(L3?Et)], or [Ni(L4?Ph)] with [RuCl2(dmso)4] (dmso = dimethyl sulfoxide) at reflux resulted in isolation of neutral dinuclear ruthenium-nickel complexes [RuCl2{(Ni(L1)}(dmso)2] (1), [RuCl2{(Ni(L2?Me)}(dmso)2] (2), [RuCl2{(Ni(L3?Et)}(dmso)2] (3), and [RuCl2{(Ni(L4?Ph)}(dmso)2] (4). Interaction of [Ni(L-R)] with [CpRu(PPh3)2Cl] (Cp? = cyclopentadienyl) at room temperature led to formation of cationic dinuclear organoruthenium-nickel complexes [CpRu{(Ni(L1)}(PPh3)]Cl (5), [CpRu{(Ni(L2?Me)}(PPh3)]Cl (6), [CpRu{(Ni(L3?Et}(PPh3)]Cl (7), and [CpRu{(Ni(L4?Ph}(PPh3)]Cl (8).
