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 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.

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.

Both (3R,5S)- and (3R,5R)-gingerdiols were synthesized. Their 1,3-diol motifs were derived from enantiopure epoxy chiral building blocks that were readily accessible from D-gluconolactone. The effect of deuterating the OH groups of the natural isomer on its optical rotation was also examined. In the course of the syntheses of the targets, an unexplored cross-metathesis (CM) reaction of unprotected 5-substituted pent-1-ene-3,5-diols was investigated, in which the CM product readily underwent an allylic epimerization and oxidation, as the starting diols rearranged into ketones with unprecedented ease. These problems were eventually resolved by performing the CM reaction in toluene in the presence of phenol. The cause of these unexpected, yet very interesting phenomena, was determined to be the presence of the unprotected OH group at C-5 of the 5-substituted pent-1-ene-3,5-diol. A mechanistic rationale is also presented. Copyright

A new amphiphilic AB2 star copolymer was synthesized by the combination of ring-opening metathesis polymerization (ROMP) and atom transfer radical polymerization (ATRP). Two different routes (methods A and B) were employed firstly to prepare the poly(oxanorbornene)-based monotelechelic polymers as the hydrophobic arm bearing dibromo-ended group via ROMP in the presence of two different terminating agents catalyzed by first generation Grubbs catalyst. The values of capping efficiency (CE) of the polymers were determined by NMR, which were 94% and 67% for methods A and B, respectively. Then, the dibromo-ended ROMP polymers were used as the macroinitiators for ATRP of 2-(dimethylamino)ethyl methacrylate (DMAEMA) to produce two hydrophilic arms. The prepared amphiphilic AB2 star copolymers poly(7-oxanorborn-5-ene-exo,exo-2,3-dicarboxylic acid dimethyl ester)-block-bis[poly(2-(dimethylamino)ethyl methacrylate)] (PONBDMn-b-(PDMAEMAm)2) with a fixed chain length of hydrophobic PONBDM and various hydrophilic PDMAEMA chain lengths can self-assemble spontaneously in water to form polymeric micelles, which were characterized by dynamic light scattering, atom force microscopy, and transmission electron microscopy measurements.

In an article, published in an article, once mentioned the application of 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer,molecular formula is C12H12Cl4Ru2, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C12H12Cl4Ru2

The rate and mechanism of substitution in the Ru(II) complexes (C1?C6) by thiourea nucleophiles was studied at pH 2 and rate constants measured as a function of nucleophile concentrations and temperature using spectrometric methods. There is increased electron density at the Ru metal atom of C2 as a result of inductive donation by substituents on the arene ligand, making it less positive and therefore less reactive than C1. For the complexes C3?C6 bearing the 2,2?-bipyridyl ligand, the aqua ligands are located trans to the arene ligands, and hence, their reactivity increases in accordance to the number and type of alkyl substituents on the eta6-arene ligands which donate inductively into the pi-molecular orbitals, causing increased trans labialisation of the coordinated aquo co-ligand. Compared to the reactivity of triaquo complex (C1), the auxiliary bipyridyl ligand of (C3) complex lowers the rate of substitution for the later complex by a factor of about 100, possibly due to its steric hindrance at the Ru(II) metal centre. The significantly negative activation entropies and positive activation enthalpies suggest an associative mode of substitution. The reactivity of the nucleophiles follow the order DMTU > TU > TMTU.
