专利号:US-8952207-B2 优先权日:2007-09-11 标题:Copper-catalyzed C—H bond arylation 发明人:DAUGULIS OLAFS; DO HIEN-QUANG 权利人:DAUGULIS OLAFS; DO HIEN-QUANG; UNIV HOUSTON SYSTEM 摘要:The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.
