Activité catalytique de dérivés du ruthénium(II) contenant le ligand triméthylyphosphine
Abstract Three ruthenium(II) complexes containing the ligand PMe3,:RuCl2(PMe3)(C6H6) (I), RuCl2(PMe3)4 (II) and RuCl2(CO)2(PMe3)2 (III) were prepared and their catalytic properties investigated. They showed activity as hydrogenation catalysts in the presence of Me2NH · BH3 and alcohol and the activity increased significantly in the order I
Die alkoholyse des triethylsilans katalysiert von [(CH3)3P]2Ru(CO)2Cl2
Abstract [(CH 3 ) 3 Pl 2 Ru(CO) 2 Cl 2 is an effective catalyst for the reaction of alcohols with triethylsilane. The rate of this reaction varies with the substituents in the hydroxy compound; it is fastest for short primary alcohols. Even in the presence of groups which can be hydrosilated (CC triple or double bonds, as well as ketones), a hydroxy group reacts preferably and completely with the silane. Kinetic experiments have been performed with the system Et 3 SiH/CH 3 CH(OH)COOEt/Ru complex.
