标题 :USE OF N-HETEROCYCLIC CARBENE-BASED COMPOUNDED NICKEL (II) COMPLEX IN SYNTHESIS OF α-BENZYL BENZOFURAN COMPOUND

摘要:Disclosed is the use of an N-heterocyclic carbene-based compounded nickel (II) complex in the synthesis of an α-benzyl benzofuran compound. In the present invention, an air-stable compounded nickel (II) complex Ni[P(OEt) 3 ]{[R`NC(CH 3 )C(CH 3 )NR`]C}Br 2 is used as a catalyst, wherein R` is 2,4,6-trimethylphenyl, and the α-benzyl benzofuran compound is synthesized by means of a hydrogen heteroarylation reaction of an aryl ethylene compound and a benzofuran compound in the presence of an organic base. The operability and substrate applicability of the catalyst are obviously better than those of the prior art, and meanwhile, the nickel catalyst has a higher practical application value due to the air stability and easiness of synthesis thereof.

摘要:The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.

标题 :Synthesis of 1,3 distributed imidazolium salts
发明人：NOLAN STEVEN P
权利人:UNIV NEW ORLEANS RES AND TECHN
摘要:Imidazolium salts are the immediate precursors to N-heterocyclic carbenes (NHC) yet a simple, general synthetic route to a wide variety of imidazolium salts is not yet available. Such a straightforward route is described for two specific members of this family of ligand precursor: 1,3-Bis(2,4,6-trimethylphenyl)imidazolium chloride (IMes.HCl) and 1,3-Bis(2,6-diispropylphenyl)imidazolium chloride (IPr.HCl). The procedure appears general and similar protocols can be used to isolate various imidazolium salts.

摘要:The subject invention provides catalytical compounds/complexes, compositions comprising such compound/complex, synthesis of the compounds/complexes, and methods of using such compounds/complexes as catalysts in, for example, carbon isotope exchange (CIE) on target bioactive molecules. Methods that allow CIE directly on drug candidates are of great importance to chemistry, biology, and medicine. Especially valuable are catalytic procedures that rely on a limited collection of available labeled materials. The instant method comprises converting a methyl group to terminal â•?CH2 utilizing transfer dehydrogenation catalysts to enable V-based olefin metathesis, followed by a hydrogenation step. The one-pot strategy allows the formal methylation/demethylation sequence and can be applied to an assortment of alkyl-containing compounds.
