标题:揭示亚表面氢抑制促进炔烃与水的电化学转移半氢化反应
摘要:摘要 与钯基电催化剂相比,以水为氢源的炔烃高选择性电催化半加氢制烯烃具有重要意义,但由于钯的过度加氢能力仍然是一个巨大的挑战.在这里,我们建议理想的钯催化剂应具有弱的烯烃吸附并抑制次表面氢的形成,以刺激炔烃半加氢的高选择性.因此,设计了以kscn为硫源的固溶界面硫化法制备硫改性pd纳米线(pd-S Nws).S的引入削弱了烯烃的吸附并阻止了活性氢(h*)扩散到pd晶格中形成不利的次表面h*.因此,在 Pd-S Nws 阴极上实现了电催化炔烃半加氢反应,该阴极具有广泛的底物范围,与电位无关的高达 99% 的烯烃选择性,非常好的脆性基团相容性以及易于合成的氘代烯烃.提出了该半加氢反应的吸附氢加成机理.重要的是,通过原位添加 Scn 轻松修改商业 Pd/c−能够以 99% 的选择性和 95% 的转化率合成克级烯烃,突出了我们方法的巨大潜力.

标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

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%.
