专利号:WO-9714698-A1 优先权日:1995-10-18 标题:Synthesis of perfluoroaryl-substituted compounds 发明人:FRAZIER KEVIN A 权利人:DOW CHEMICAL CO 摘要:Perfluoroaryl-substituted compounds are prepared from perfluoroaryl compounds, particularly tris pentafluorophenyl borane is prepared from hexafluorobenzene. The method comprises contacting a perfluoroaryl compound with an organomagnesium reagent in the presence of a catalyst to form a perfluoroaryl magnesium compound, and contacting the perfluoroaryl magnesium compound with a trihalide element to form a tris perfluoroaryl-substituted compound.
专利号:WO-2015131100-A1 优先权日:2014-02-28 标题:Ligand-controlled c(sp3)-h arylation and olefination in synthesis of unnatural chiral alpha amino acids 发明人:YU JIN-QUAN 权利人:SCRIPPS RESEARCH INST 摘要:The use of ligands to tune the reactivity and selectivity of transition metal-catalysts for C(-sp3)-H bond functionalization is a central challenge in synthetic organic chemistry. Herein, we report a rare example of catalyst-controlled C(sp3)-H arylation using pyridine and quinoline derivatives: the former promotes exclusive monoarylation, whereas the latter activates the catalyst further to achieve diarylation. Successive application of these ligands enables the sequential diarylation of a methyl group in an alanine derivative with two different aryl iodides, affording a wide range of β-Ar-p-Ar ' -cc-amino acids with excellent levels of diastereoselectivity (d.r. > 20:1). Both configurations of the β-chiral center can be accessed by choosing the order in which the aryl groups are installed. The use of a quinoline derivative as a ligand also enables C(sp3)-H olefination of a protected alanine.
专利号:US-5026929-A 优先权日:1990-02-08 标题:Synthesis of highly fluorinated aromatic compounds 发明人:MARSELLA JOHN A; PEZ GUIDO P; COUGHLIN ANNE M 权利人:AIR PROD & CHEM 摘要:A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.
