- Аннотация: Chloride abstraction from [Ru{HB(pz)(3)}(tmen)Cl] (pz = pyrazolyl, tmen = Me(2)NCH(2)CH(2)NMe(2)) with NaBPh(4) in the solvents acetone and dimethylformamide led to the formation of the respective cationic [Ru{HB(pz)(3)}(tmen)(solv)](+) complexes. In the presence of phenylacetylene, these are easily transformed into the first example of a ruthenium HB(pz)(3) vinylidene complex. Extended-Huckel molecular-orbital calculations have been performed to establish the nature of the bonding involved. From [Ru{HB(pz)(3)}(py)(2)Cl] (py = pyridine) the corresponding vinylidene complex could be prepared in the same way, although the intermediate solvent complexes could not be isolated. Selected crystal structures were determined.
