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

Rosario Scopelliti, Kay Severin, 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 ...
