标题:黄原酸酯介导的以水为氢供体的炔烃半加氢合成(e)-烯烃†
摘要:炔烃的半氢化是在实验室制备和工业中获得烯烃的最广泛使用的方法之一.过渡金属催化剂已针对此转化进行了广泛研究,但对吡啶,-Oh,-Nh 2,-Bpin和卤化物等官能团的耐受性以及微量过渡金属催化剂的毒性仍极具挑战性.在这项研究中,我们报告了使用廉价的市售黄药作为介质,实现炔烃半加氢的通用且稳健的策略.机理研究支持非自由基过程,H 2 O充当氢供体.

标题:Method of regioselective synthesis of substituted benzoates
发明人：KRAUS GEORGE A
权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC
摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.

发明人：ARRETZ EMMANUEL
权利人:ELF AQUITAINE EXPLORATION PROD
摘要:This process for the synthesis of 3-mercaptopropionic acid esters by addition reaction of H2S to the corresponding acrylic acid ester is carried out in the presence of a solid-support functionalized with basic guanidine functional groups, on condition that these groups are free of hydrogen that is directly attached to a nitrogen atom.
