The reactions of RuCl2[P(C6H5)3]3, RuCl2(tmeda)2, and RuCl2(1,5-COD)(tmeda) with polybasic amines such as pyrazole have been studied. From the phosphine complex, a binuclear complex has been isolated in which one pyrazole has been incorporated, while reactions of the latter two with excess pyrazole lead to the replacement of a tmeda ligand by two pyrazoles.
Graphical abstractThe reaction of RuCl2[P(C6H5)3]3 with one equivalent of pyrazole led to the incorporation of one pyrazole in a di(ruthenium) complex, presumably reflecting an instability of a 1:1 complex. The reaction of pyrazole with RuCl2(tmeda)2 has led to the isolation of RuCl2(tmeda)2(C3N2H4)2. Both species, as well as RuCl2(tmeda)2 and RuCl2(1,5-COD)(tmeda), have been structurally characterized.Figure optionsDownload full-size imageDownload as PowerPoint slide
