摘要:本文介绍的是一组双金属和三金属"配位促进剂-催化剂"组件,其中配位化合物[ruii(terpy)2]和[osii(terpy)2]充当增强[ruii(nhc)的催化活性的催化剂)(对伞花烃)为基础的催化位点.在烯烃和炔烃氧化成相应的醛,酮和二酮的过程中,助催化剂加速了对甲基苯甲基从催化部位的氧化损失,从而生成了活性催化剂.发现在这些组件中,[osii(terpy)2]单元的增强效率明显高于其同类物[ruii(terpy)2]单元.进行了机理研究以了解这种独特的改进.

摘要:Copper(II) bromide mediated oxidation of acylated enol and use of the reaction in the synthesis of α,β-unsaturated or α-bromo ketones or aldehydes are disclosed. The method provides an efficient and practical process for manufacturing dehydrohedione (DHH) and many other versatile α,β-unsaturated or α-bromo ketones or aldehydes in large scales to avoid using precious metal compounds.

摘要:This invention provides non-steroidal estrogen receptor ligands having a modular structure that is amenable to solid phase synthesis and the application of combinatorial synthetic methods to prepare these estrogen receptor ligands. ER ligands of this invention consist of a core scaffold that is a carbocyclic or heterocyclic-5-member ring that has two double bonds or a 6-member aromatic ring. A plurality of selected substituents are bonded to the ring substantially independently of other substituents. The modular structure of these compounds allows for synthesis of a very large numer of substituent structural variations, substituent combinations and substituent positioning on the core. The structural variants of the ER ligands of this invention exhibit a spectrum of selective affinities for ERα and ERβ and a spectrum of agonist/antagonist properties.

摘要:This invention provides novel polyethers and polycarbonates which exhibit nonlinear optical response, and which have utility as a transparent optical component in optical light switch and high modulator devices. n These polyethers and polycarbonates are the polymerization product of one or more monomers having the formula ##STR1## in which Z is a conjugated heterocyclic substituent having a NO 2 or a CN group. Further, the invention relates to a method of making the polycarbonate by a ring opening polymerization in the presence of an electric field. In a separate embodiment, the invention relates to non-linear optical devices made with these polymers.
