Located in the middle of fever to solve problem CO2 emissions environment, sequestration by reaction with epoxides is one key tools, as it not only fixes CO2, but also makes functional leading cyclic carbonates. Herein, results are focused specifically on formation organic carbonates catalyzed metal-salen complexes, previously achieved yttrium and scandium, that compared those analogous complex...

Highly enantioselective and good to high-yielding aziridination of conjugated and non-conjugated terminal olefins and cyclic olefins was achieved using a newly designed Ru(CO)(salen) complex as the catalyst in the presence of SESN(3) under mild conditions.

Oxygenation Catalyst, Cobalt Schiff-Base Complex, Crystal Structure, Electrochemistry N,N'-Bis(salicylidene)ethylenediaminatocobalt(III) hydroxide is treated with chloroform in methanol to yield the corresponding chloride in pure, crystalline form. Results of the crystal structure determination compare well with those in earlier reports of dimeric [Co(salen)Cl]2 units and incorporated CHC13 mol...

(Salen)Mn(III) catalysts show increased turnover numbers in the catalytic asymmetric epoxidation of conjugated olefins upon addition of bulky Lewis acids (LA) such as zinc tetraphenylporphyrin (ZnTPP). Up to 3-fold increase in total catalytic activity and at least a 20-fold increase in catalyst stability was observed with a (salen)Mn catalyst bearing pendant 5,5′-bis-pyridyl groups. This latter...

We report the synthesis of the first 2',3'-diamino substituted uridine derivative with xylo-configuration, its use as starting material for the synthesis of salen-type ligands and the first structurally characterised copper(II) complex thereof.

DNA G-rich sequences are able to form four-stranded structures organized in stacked guanine tetrads. These structures, called G-quadruplexes, were found to have an important role in the regulation of oncogenes expression and became, for such a reason, appealing targets for anticancer drugs. Aiming at finding selective G-quadruplex binders, we have designed, synthesized and characterized a new w...

A chiral Mn(salen) complex exhibiting two lactam binding sites at two rigid 1,5,7-trimethyl-3-azabicyclo[3.3.1]nonan-2-one skeletons is capable of enantioselective sulfoxidation due to spatially remote substrate hydrogen bonding.

A new lipophilic Ru salen complex with cholesterol groups can be efficiently incorporated into liposome bilayers, allowing the photoinduced release of nitric oxide (NO) and the membrane transport of NO to coexisting liposomes.

The solid catalyst with high catalytic activity and enantioselectivity in the hydrolytic kinetic resolution (HKR) of epoxides was prepared by confining Co(Salen) in the nanocage of SBA-16 through reducing the pore entrance size using a silylation method. It was found that the activity of the solid catalysts increased with the number of [Co(Salen)] molecules per nanocage increasing, and the soli...
