标题:芳基和烷基取代的末端炔烃的α-选择性镍催化氢铝化:内部乙烯基铝,卤化物或硼酸盐的实际合成
摘要:描述了一种用于末端炔烃的 Ni 催化加氢铝化的方法,可有效地形成 α-乙烯基铝异构体(在 2-12 小时内转化率 >98%)并具有高选择性(95% 至 >98% α).催化 α 选择性氢化铝化反应在试剂(二异丁基氢化铝;Dibal-H)和 3.0 Mol% 金属配合物(ni(Dppp)Cl(2)) 的存在下进行,这些金属配合物是市售且价格低廉的.在相同条件下,但使用 Ni(Pph(3))(2)Cl(2) 时,加氢铝化具有高度的 Beta 选择性,并且与使用 Dibal-H 的未催化转化不同,生成很少或不生成炔铝副产品.所有加氢金属化反应都是可靠的,操作简单且实用的,并且提供了各种不容易获得的乙烯基铝.衍生的α-乙烯基卤化物和硼酸酯可以通过用合适的亲电子试剂[例如,分别为br(2)和甲氧基(频哪醇)硼]直接处理来合成.Ni 催化的氢氧化铝可以使用低至 0.1 Mol% 的催化剂以克级规模进行,具有同样高的效率和选择性.

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 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis
发明人：SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J
权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.
