Reference of 246047-72-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium. In a document type is Article, introducing its new discovery.

A new Grubbs-Hoveyda-Blechert alkene metathesis catalyst, in which the benzylidene ligand has been coordinated to a highly electron-withdrawing tricarbonylchromium moiety, is presented. The structure of the complex provides evidence for a so far unreported attractive interaction between the benzylidene hydrogen atom and one of the mesityl substituents at the Arduengo carbene ligand. Screening of the catalytic properties shows that the activity of the new catalyst in ring-closing, enyne, cross, and homo metathesis of alkenes is comparable and in some cases better than that of known catalysts.

A new [2]rotaxane host system containing nitro-isophthalamide macrocycle and polyether functionalised pyridinium axle components is prepared via clipping and stoppering synthetic methodologies using chloride anion templation. After removing the chloride anion template, 1H NMR titration experiments reveal the unique interlocked host cavity to be highly selective for binding chloride and bromide in preference to basic oxoanions in competitive aqueous solvent mixtures. The rotaxane host system proved to be a superior anion complexant in comparison to the individual macrocycle and axle components. The anion binding affinity of the novel rotaxane is also investigated via molecular dynamics simulations and in general the structural data obtained corroborates the experimental solution anion recognition behaviour.

The enantioselective total synthesis of the bioactive marine natural products pinnaic acid and halichlorine is reported in detail. Our total synthesis features the construction of the five-membered ring and C9 and C13 stereogenic centers through a palladium-catalyzed trimethylenemethane [3+2] cyclization; the installation of the nitrogen atom through a regioselective Beckmann rearrangement of a poorly reactive ketone; the stereoselective cyclization of the spiro ring through a four-step, one-pot hydrogenation- cyclization; and efficient connection of the sterically hindered lower chain through a reduced-pressure cross olefin metathesis reaction.

A sixteen-step synthesis of the twelve-membered macrolide (-)-cladospolide B (2) from the microbially-derived cis-1,2-dihydrocatechol 5 is described. Pivotal steps include the ring-closing metathesis (RCM) of diene 12 to give the ten-membered lactone 13 together with small amounts of the head-to-tail and head-to-head dimers 14 and 15, respectively. The saturated lactol 19 derived from compounds 13 and 14 readily participates in a Wadsworth-Horner-Emmons reaction to give the E-configured alpha,beta-unsaturated ester 20. This last compound is then converted, through application of a Yamaguchi lactonisation reaction on the derived acid 22, into the macrolide 23 which, upon removal of the bis-acetal protecting group, affords compound 24, the E-isomer of target 2. Irradiation of a benzene solution of compound 24 results in its partial photoisomerisation to (-)-cladospolide B (2). The Royal Society of Chemistry 2005.

A cat. for all seasons: The transformation of the allenylidene-ruthenium complexes [RuCl(eta6-arene) (=C=C=CR2) (PR? 3)] [CF3SO3] into indenylidene species [RuCl(eta6-arene) (indenylidene) (PR?3)] [CF 3SO3]2 by the simple protonation with CF 3SO3H and formation of an alkenylcarbyne intermediate (see picture; arene = p-cymene) is observed by low temperature NMR experiments. The new in situ generated 18 electron ionic indenylidene species are highly active in the polymerization of cyclooctene and cyclopentene, ring-closing metathesis of dienes and enynes, and the acyclic diene metathesis of decadiene, thus making it a catalyst for all seasons.

A new type of functionalization of cyclosiloxane and cyclosilazane is reported. Commercially available vinyl-substituted cyclosiloxane and cyclosilazane can be converted chemo- and regioselectively to styryl- and beta-alkoxyvinyl-substituted derivatives via respective silylative coupling reactions with styrene and vinyl alkyl ethers catalyzed by RuHCl(CO)(PCy 3)2. The obtained cis-tristyrylcyclotrisiloxane showed a unique arrangement of the three styryl groups through face-to-face and side-by-side pi-pi interactions. Pd-catalyzed Hiyama coupling reaction of synthesized beta-n-butoxyvinyl-substituted cyclosiloxane with iodobenzene was also performed to afford beta-n-butoxystyrene regioselectively.

Cadmium selenide nanoparticles, prepared by known methods, were stabilized with functional phosphine oxide 1, then used to support the polymerization of cyclic olefins radially outward from the surface by ruthenium-catalyzed ring-opening metathesis polymerization (ROMP). The conversion of compound 1 into the new metathesis catalyst 3 by carbene exchange and the subsequent polymerization of cyclic olefins were observed spectroscopically by 1H NMR to afford for example CdSe-polycyclooctene composite 6. Transmission electron micrographs on thin films of these composites showed good nanoparticle dispersion. This is in stark contrast to the substantial nanoparticle aggregation observed when similar polymerizations were performed in the presence of conventional TOPO-covered nanoparticles. The methods reported here to prepare composite product 6 are applicable to other cyclic olefins, and suggest that this chemistry will be useful for incorporating CdSe nanoparticles into a wide variety of polymer matrices.
