20090076266 | COPPER-CATALYZED C-H BOND ARYLATION - 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. | 03-19-2009 |
20090105475 | PROCESS FOR PRODUCING 2,3-DIHYDROPYRIDAZINE COMPOUND - A process for producing a 2,3-dihydropyridazine compound represented by the formula (2): | 04-23-2009 |
20090234118 | Ionic Liquids - The present invention relates to compositions of matter that are ionic liquids, the compositions comprising any of eleven cations combined with any of three fluorinated sulfonated anions. Compositions of the invention should be useful as solvents and, perhaps, as catalysts for many reactions, including aromatic electrophilic substitution, nitration, acylation, esterification, etherification, oligomerization, transesterification, isomerization and hydration. | 09-17-2009 |
