标题:通过阿魏酸脱羧酶的非氧化酶促脱羧从丙烯酸衍生物中反应生成末端烯烃
摘要:真菌阿魏酸脱羧酶 (Fdc) 属于 Ubid 酶家族,通过使用异戊二烯化黄素辅因子催化肉桂酸衍生物的可逆(脱)羧化.后者由黄素异戊烯基转移酶 Ubix 合成.在此,我们证明了 Fdc/ubix 表达细胞对于分离酶和全细胞生物催化的适用性. Fdc表现出高活性,总周转数(Ttn)高达55000,周转频率(Tof)高达370 Min-1 .共溶剂相容性研究表明,Fdc 对某些有机溶剂的耐受性高达 20% V/v.利用 Holo-Fdc 的体外(脱)羧酶活性以及全细胞生物催化剂,我们对三种 Fdc 进行了底物分析研究,为活性的结构决定因素提供了见解. Fdc 对多种 C3 处带有(杂)环或烯属取代基的丙烯酸衍生物表现出广泛的底物耐受性,转化率高达 >99%. Fdc 的合成效用通过制备规模的脱羧得到了证明.

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.

标题:Method for the continuous synthesis of a diene elastomer with lithium amide initiator
发明人：DIRE CHARLOTTE; DESSENDIER MARIE-HÉLÈNE
权利人:MICHELIN & CIE
摘要:A process for the continuous synthesis of a diene elastomer is provided. The synthesis is conducted by means of n reactors r1 to rn, considered to be continuous stirred-tank reactors, which are equipped with an internal stirring system. The reactors are arranged in series, n varying from 2 to 15, preferably from 2 to 9. The reactor r1 is fed by an input solution comprising a solvent, one or more monomer(s), an anionic polymerization initiator chosen from lithium amides and a polar agent. The conversion by weight C1 in the first reactor is less than 70%, and the total conversion by weight Cn at the outlet of the reactor rn is greater than or equal to 70%.

摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.
