Multifaceted Chemistry of [(Cymene)RuCl2]2 and PCy3

Kay Severin, Rosario Scopelliti, Euro Solari, Sébastien Gauthier

The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...

Heterobimetallic complexes as catalyst precursors for the Oppenauer-type oxidation of alcohols

Kay Severin, Sébastien Gauthier

A heterobimetallic Ru(II)-Rh(I) complex has been identified as a potent catalyst precursor for the Oppenauer-type oxidation of alcohols. With 0.1-0.5 mol% of this complex and K2CO3 as the co-catalyst, it is possible to oxidize secondary and primary alcohol ...
