标题 :Method for preparing a bimetallic ruthenium/tin catalyst and a process for the synthesis of aldehydes
发明人：JACQUOT ROLAND
权利人:RHODIA CHIMIE SA
摘要:The present invention relates to a new process for the preparation of a bimetallic ruthenium/tin catalyst. The process for the preparation of a bimetallic ruthenium/tin catalyst according to the invention is characterised by the fact that it consists in carrying out the reduction of a ruthenium complex having an electrovalency of -4 and a coordination number of 6, the ligands being either a halogen atom or an anion or a tin halide. The catalyst is further employed for the preparation of aldehydes by reduction, in the vapor phase, of carboxylic acids, esters and anhydrides.

标题:Use of aryl chlorides in palladium-catalyzed C-H bond functionalization
发明人：DAUGULIS OLAFS; CHIONG HENDRICH
权利人:DAUGULIS OLAFS; CHIONG HENDRICH; UNIV HOUSTON SYSTEM
摘要:A one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using chloroarenes and palladium catalysts is disclosed. 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.
