标题:Process for the synthesis of 2-hydroxyphenyl alkyl ketones
发明人：BORZATTA VALERIO; POLUZZI ELISA; VACCARI ANGELO
权利人:ENDURA SPA
摘要:A process is described for the synthesis of 2-hydroxyphenylalkyl ketones, by means of catalytic rearrangement of phenolic esters. This process is characterized by the use, as catalysts, of crystalline aluminosilicates of the pentasyl type having predefined values of silica/alumina ratio, grain size, surface area and porosity, and containing between 10 wt% and 40 wt% of finely ground alumina as bonding agent. The rearrangement thus catalyzed involves a high conversion of the phenolic ester, a high orthoselectivity and a low formation of phenolic by-products, thus enabling the formation of the end product in high yields. In particular, the process applies to the synthesis of 2-hydroxyacetophenone.

权利人:GOODYEAR TIRE & RUBBER
摘要:The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.

发明人：KANTER JAMES; MARLOWE CHARLES; PANDEY ANJALI; MULLINS JOHN J G; SCARBOROUGH ROBERT; BUTKE GREG; JACOBSON BARRY; WALKER DEREK
摘要:Disclosed are processes for producing a (2S) or (2R) 4-oxo-chroman-2-yl acyl compounds and chroman-2-yl acyl compounds, esters or amides thereof as well as derivatives thereof. Such processes may involve chiral synthesis or achiral synthesis, preferably coupled with a resolution procedure. Such compounds, particularly (2S) or (2R) acetic acid esters, are useful intermedates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are processes for making derivatives of such substantially pure, or enhanced compositions of single (2R) or (2S) enantiomer intermediates or processes for producing final products or salts from such desired enantiomers.

标 题:Application of cationic iron(iii) complex containing 1,3-di-tert-butylimidazolium in synthesizing arylbenzyl ether compounds

摘要:Disclosed is an application of an iron (III) complex containing 1,3-di-tert-butyl imidazolium cation in synthesizing arylbenzyl ether compounds. Specifically, di-tert-butyl peroxide is used as an oxidant, and a corresponding arylbenzyl ether compound can be synthesized by means of an oxidative coupling reaction between a phenolic compound and a toluene compound. In the present invention, an iron (III) complex is used as a catalyst for the first time, which achieves the oxidative coupling between a phenolic compound and a toluene compound. The foregoing is the first oxidative coupling reaction between a phenolic compound and benzylic C(sp 3 )-H bond, which provides a new method for the synthesis of arylbenzyl ether compounds. Compared with existing synthesis methods, the present invention avoids the use of toxic and polluting halogenated hydrocarbons and strong bases, has better atom economy, and conforms to the development concept of green synthetic chemistry.
