标题:催化,逆热力学位置烯烃异构化
摘要:C=c双键的位置异构化是烯烃区域异构体相互转化的有力策略.然而,现有方法提供了从不太稳定的起始材料获得热力学上更稳定的异构体的途径.在这里,我们报告了在光化学辐照下促进逆热力学位置烯烃异构化的双催化剂系统的发现,提供了直接从共轭的内部烯烃起始材料获得末端烯烃异构体的途径.该方法的实用性在多种富电子/贫电子烯烃的去共轭中以及通过对天然产物合成的战略应用得到证明.机理研究与区域特异性双分子均裂取代(s H2') 机制通过烯丙基钴肟中间体进行.

标题:Method for the synthesis of aliphatic carboxylic acids from aldehydes
发明人：SPRINGER HELMUT; LAPPE PETER
权利人:CELANESE CHEM EUROPE GMBH
摘要:The invention relates to a method for the synthesis of aliphatic carboxylic acids by the catalytic oxidation of aldehydes with oxygen, or oxygen-containing gas mixtures. Metals of groups 5 11 of the periodic table of elements, or the compounds thereof are used as catalyst, in amounts of up to 5 ppm, based upon the amount of aldehyde used.

标题 :Synthesis of tertiary mercaptans from isobutylene homopolymers
发明人：ARRETZ EMMANUEL
权利人:ELF AQUITAINE
摘要:The invention relates to the synthesis of tertiary mercaptans from isobutylene homopolymers and from hydrogen sulphide by means of heterogeneous catalysis. In the processs according to the invention, the reaction is carried out at a temperature below 45 DEG C., preferably between 0 DEG and 35 DEG C., in the presence of a catalyst consisting of a dry cation exchange resin. Excellent yields of tertiary mercaptan are thus obtained, while the formation of undesirable byproducts is virtually avoided.

标题 :Superacidic catalysts for the synthesis of methyl-tert-butyl ether (MTBE)
发明人：MAO RAYMOND LE VAN
权利人:QUEBECOISE D INITIATIVES PETRO
摘要:In accordance with the present invention, there is now provided a novel selective catalyst useful for the synthesis of methyl-tert-butyl ether (MTBE) or ethyl-tert-butyl ether (ETBE) prepared by reacting isobutene with methanol or ethanol, respectively. More specifically, the catalyst of the present invention comprises from about 0.5 to about 7% by weight of triflic acid (trifluoro-methanesulfonic acid, CF3SO3H, hereafter referred to as TFA) incorporated onto an acid form Y zeolite.
