Vinylidene rutheniums with an electrostructurally-flexible NO ligand and their ruthenacyclobutene formation.
Vinylidene ruthenium complexes were prepared from trichloronitrosylbis(phosphine)rutheniums and terminal alkynes, subsequent cycloaddition of methyl propiolate to the vinylidene complexes giving rise to unusual ruthenacyclobutene species; in these transformations, an interesting electrostructurally-flexible behaviour of the NO ligand was observed.
