A document type is Article, introducing its new discovery.

Five new complexes [RuCl2(SIMes)(Ind)(O-pXC5H4)] bearing different para-substituted triphenylphosphites (X = H, OCH3, CF3, Cl, SF5 and CN) were synthesised and used to study the effect of the electronic properties of the phosphite on olefin metathesis activity. Investigations of the physical properties of the new ligands and complexes were performed using physicochemical and DFT calculations. The catalytic activity of the complexes was benchmarked in challenging ring closing metathesis transformations featuring the formation of tetra-substituted double bonds. Complex [RuCl2(SIMes)(Ind)P(O-pCF3C5H4)3] (3c) exhibited a particularly high catalytic activity, superior to state-of-the-art catalysts, and was further tested on a wide range of substrates.

To enable positron emission tomography (PET) imaging of the in vivo kinetics of ubiquinone and ubiquinol, which is referred to as coenzyme Q10, their 11C-radiolabeled counterparts were synthesized herein. 11C-Labeled ubiquinone [11C]-1 was realized by Pd-mediated rapid C-[11C]methylation of [11C]CH3I with 39-demethyl-39-(pinacolboryl)ubiquinone, prepared by Ru-catalyzed olefin metathesis of unradiolabeled ubiquinone with 2-(pinacolboryl)propene. Subsequent reduction of [11C]-1 using Na2S2O4 yielded 11C-labeled ubiquinol [11C]-2. The synthesis time and [11C]CH3I-based radiochemical yield of [11C]-1 were within 36 minutes and up to 53%, while those of [11C]-2 were within 38 minutes and up to 39%, respectively. After radiopharmaceutical formulation, the qualities of [11C]-1 and [11C]-2 were confirmed to be applicable for animal PET studies. The analytical values of [11C]-1 and [11C]-2 are as follows: radioactivity of up to 3.5 and 1.4 GBq, molar activity of 21 to 78 and 48 to 76 GBq/mumol, radiochemical purity of greater than 99% and greater than 95%, and chemical purity of greater than 99% and 77%, respectively. The concept behind this radiolabeling procedure is that unradiolabeled natural ubiquinone can be converted to 11C-radiolabeled ubiquinone and ubiquinol via a pinacolborane-substituted ubiquinone derivative. Each PET probe was used for molecular imaging using rats to investigate the in vivo kinetics and biodistribution of the coenzyme Q10.

Allylic chlorides prepared from commercially available trans-1,4-dichloro-2-butene were converted to trans-disubstituted 5- and 6-membered ring systems with perfect diastereoselectivity and high enantioselectivity under chiral ruthenium catalysis. These products contain stereodefined secondary and tertiary alcohols that originate from the trapping of an alkylruthenium intermediate with adventitious water. Key to the success of this transformation was the development of a new BINOL-based phosphoramidite ligand containing bulky substitution at its 3- and 3?-positions. As a demonstration of product utility, diastereoselective Friedel-Crafts reactions were performed on the chiral benzylic alcohols in high yield and stereoselectivity.

The reaction of SnCl2 with the Ru-Cl bond of the Grubbs I catalyst RuCl2(=CHPh)(PCy3)2 (1) gives the complex {[Ru(=CHPh)(SnCl3)(PCy3)]2(mu-Cl) 3}-[HPCy3]+ (2), but containing two diethyl ether solvate molecules. The formal insertion of SnCl2 into one Ru-Cl bond of the Hoveyda II catalyst RuCl2(=CH-C 6H4OPri)(H2IMes) (3) (H 2IMes = N,N?-dimesityl-4,5-dihydroimidazol-2-ylidene) results in formation of the new complex RuCl(SnCl3)(=CH-C6H 4OPri)(H2IMes) (4). The X-ray analyses of 2 and 4 show the presence of very short Ru-Sn bonds (2.5834(9) A mean bond for 2 and 2.5925(12) A for 4) and the retention of short Ru=C bonds (1.895(10) and 1.825(8) A, respectively). Complex 4 shows an excellent catalytic activity for the cross-metathesis of plant oil derivatives, the C11 omega-unsaturated ester and aldehyde and the unsaturated C18 diester with acrylonitrile, and a good activity for their cross-metathesis with methyl acrylate. Good to excellent yield of alpha,omega-bifunctional compounds, precursors of polyesters and polyamides, were obtained. Complex 2 shows catalytic activity for the self-metathesis of C11 omega-unsaturated aldehyde at low concentration to produce C20 alpha,omega-dialdehyde.

The modification of methyl ricinoleate by etherification of the hydroxyl group was accomplished by using a nonclassical ruthenium-catalyzed allylation reaction and also by esterification. Methyl ricinoleate derivatives were engaged in ring-closing metathesis (RCM) reactions leading to biosourced 3,6-dihydropyran and alpha,beta-unsaturated lactone derivatives with concomitant production of polymer precursors. Sequential RCM/hydrogenation and RCM/cross-metathesis were also implemented as a straightforward method for the synthesis of tetrahydropyran and lactone derivatives as well as valuable monomers (i.e., polyamide precursors).

A simple and generic approach to access a new family of Ru-alkylidene olefin metathesis catalysts with specialized properties is reported. This strategy utilizes a late stage, utilitarian Hoveyda-type ligand derived from tyrosine, which can be accessed via a multigram-scale synthesis. Further functionalization allows the catalyst properties to be tuned, giving access to modified second-generation Hoveyda-Grubbs-type catalysts. This divergent synthetic approach can be used to access solid-supported catalysts and catalysts that function under solvent-free and aqueous conditions.

Reference of 301224-40-8, An article , which mentions 301224-40-8, molecular formula is C31H38Cl2N2ORu. The compound – (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride played an important role in people’s production and life.

A new family of ruthenium-based olefin metathesis catalysts bearing a series of thiazole-2-ylidene ligands has been prepared. These complexes are readily accessible in one step from commercially available (PCy 3)2Cl2Ru=CHPh or (PCy3)Cl 2Ru=CH(o-iPrO-Ph) and have been fully characterized. The X-ray crystal structures of four of these complexes are disclosed. In the solid state, the aryl substituents of the thiazole-2-ylidene ligands are located above the empty coordination site of the ruthenium center. Despite the decreased steric bulk of their ligands, all of the complexes reported herein efficiently promote benchmark olefin metathesis reactions such as the ring-closing of diethyldiallyl and diethylallylmethallyl malonate and the ring-opening metathesis polymerization of 1,5-cyclooctadiene and norbornene, as well as the cross metathesis of allyl benzene with cis-1,4-diacetoxy-2-butene and the macrocyclic ring-closing of a 14-membered lactone. The phosphine-free catalysts of this family are more stable than their phosphine-containing counterparts, exhibiting pseudo-first-order kinetics in the ring-closing of diethyldiallyl malonate. Upon removing the steric bulk from the ortho positions of the N-aryl group of the thiazole-2-ylidene ligands, the phosphine-free catalysts lose stability, but when the substituents become too bulky the resulting catalysts show prolonged induction periods. Among five thiazole-2-ylidene ligands examined, 3-(2,4,6-trimethylphenyl)-and 3-(2,6-diethylphenyl)-4,5-dimethylthiazol-2- ylidene afforded the most efficient and stable catalysts. In the cross metathesis reaction of allyl benzene with cis-1,4-diacetoxy-2-butene increasing the steric bulk at the ortho positions of the N-aryl substituents results in catalysts that are more Z-selective.
