摘要:高价金属氧物种是许多金属酶催化循环中氧原子转移步骤的关键中间体.尽管此类酶的氧化还原活性金属中心通常由阴离子氨基酸侧链或卟啉环支撑,但肽主链可能充当强电子给体配体,以稳定高氧化态.为了测试这种想法在合成环境中的可行性,我们准备了一种新的酰胺基多齿配体的镍(II)配合物.该n5配体的单核镍配合物通过使用mcpba作为末端氧化剂来催化多种烯烃的环氧化反应.值得注意的是,对于末端烯烃底物观测到非常高的催化效率和选择性.我们发现,次级配位球的质子化是催化循环的入口,在催化循环中,随后形成高价镍物种进行氧转移反应.概念上平行的过程可能允许金属酶通过在次级配位领域使用质子开关来控制初级配位领域的催化循环.

摘要:Vehicles, which are water dilutable after neutralization with bases, have an acid number of 5 to 60 and are obtainable by polymerization or copolymerization of 10 to 90 parts by weight of one or several acidic, phosphoric acid-functional unsaturated monomers, which are polymerizable by a free radical mechanism and can be present in admixture with one or several ethylenically unsaturated monomers, which are also polymerizable by a free radical mechanism, with addition of a free radical initiator, in the presence of 90 to 10 parts by weight of one or several epoxide resins or modified epoxide resins, in one or several solvents. Methods of synthesizing them, aqueous coating materials containing them and their use.

摘要:(2-hydroxyalkyl)-substituted beta-dicarbonyl compounds are produced by reacting beta-dicarbonyl compounds having the formula R?1-CO-CH2?-CO-R?2, in which R?1 and R?2 represent independently from each other alkyl, cycloalkyl, aryl or alkoxy residues with 1 to 6 carbon atoms, with 1,2-epoxyalkanes having formula (II), in which R?3 represents an alkyl residue with 6 to 24 carbon atoms, in the presence of polyalkylene glycolethers and/or anorganic or organic bases. The beta-dicarbonyl compounds thus produced are useful as starting materials for the production of heterocyclic compounds for the synthesis of dyes, pharmaceuticals and plant protective products.
