Well-defined liquid crystal networks with controlled molecular weight between cross-links and cross-link functionality were prepared by “click” cross-linking of telechelic polymers produced by ring-opening metathesis polymerization (ROMP). The networks readily swell in a small molecule liquid crystal, 5CB, to form LC gels with high swelling ratios. These gels exhibit fast, reversible, and low-threshold optic switching under applied electric fields when they are unconstrained between electrodes. For a given electric field, the LC gels prepared from shorter telechelic polymers showed a reduced degree of switching than their counterparts made from longer polymer strands. The reported approach provides control over important parameters for LC networks, such as the length of the network strands between cross-links, cross-linker functionality, and mesogen density. Therefore, it allows a detailed study of relationships between molecular structure and macroscopic properties of these scientifically and technologically interesting networks.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

We present the synthesis of five- and six-membered cyclic phenylalanine mimics (1, 9, 16 and 17) that are constrained in a proline-like conformation. The five-membered mimetic 16 was prepared by Ring Closing Metathesis (RCM) of diene 15, itself prepared by alpha-benzylation of the L-methionine derived oxazolidinone 10, followed by oxidative elimination, ring hydrolysis and N-allylation. The six-membered mimetic 1 was prepared by allylating the L-phenylalanine-derived oxazolidinone 5, followed by hydrolysis, N-allylation and RCM. Olefins 1 and 16 were catalytically hydrogenated to give 9 and 17, respectively. The solid state structures of 9 and 16 were determined by X-ray crystallography and their conformations compared with that of 1.

A smooth transition from (R)-carvone to a beta-lactone and then to (+)-omphadiol characterizes the first total synthesis of this sesquiterpene, which was achieved in ten steps and 18 overall yield. All six contiguous stereogenic centers were introduced in a highly diastereoselective manner. Key steps include a nucleophile-promoted aldol lactonization, a single-pot, sequential intra-/intermolecular dialkylation, a tandem olefin isomerization/RCM, and a cyclopropanation with unusual facial selectivity.

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.

The reaction of a ruthenium carbide complex RuCl2(C:) (PCy 3)2 with [H(Et2O)x] +[BF4]- at a molar ratio of 1:2 produced a two-core ruthenium carbene complex {[RuCl(CHPCy3)(PCy 3)]2(mu-Cl)3}+·[BF 4]- (8) in the form of a yellow-green crystalline solid. After a ligand exchange reaction of 8 with LiBr, a bromide ruthenium carbene complex {[RuBr(CHPCy3)(PCy3)]2(mu-Cl) 3}+·[BF4]- (9) was obtained as a crystalline solid. Catalytic studies showed that both 8 and 9 are selective catalysts for ring closing metathesis of unsubstituted terminal dienes. More importantly, no isomerized byproduct was observed when 8, or 9 was used as the catalyst at an elevated temperature (137 C), indicating that both 8 and 9 are chemo-selective catalysts for ring closing metathesis reactions.
