A series of [P,N]-phosphinobenzimidazole ligands is reported in which the charge (anionic vs. neutral) and size of the N -substituent of the benzimidazole scaffold has been varied. In order to evaluate the impact of the substituent's properties on th

The ligand electron-donating abilities are compared among a series of monodentate, anionic (phosphino)tetraphenylborate phosphines [Ph4P][Ph2P-R-C6H4BPh3] (R = –C6H4–, –CH2–, –CH2CH2– or none), and their neutral counterparts Ph2PR (R = bi

A new anionic [P,N]-hybrid ligand based on a phosphinobenzimidazole scaffold and functionalized with a tetraphenylborate substituent is reported. This new anionic ligand readily chelates to a variety of ruthenium-cyclopentadienyl and -pentamethylcycl

The acetonitrile ligands in [(PhB(CH2PPh2)3-κ3P)Ru(NCMe)3]PF6 (1) (which contains a facially coordinated anionic tripodal phosphine ligand) are labile and are rapidly replaced by other ligands, although the steric profile of the phosphine ligand lim

The synthesis and characterization of a series of ruthenium carbyne complexes supported by either pentamethylcyclopentadienyl (Cp*) or hydridotris(pyrazolyl)borate (Tp) ligands are discussed. Reacting the neutral ruthenium(II) vinylidenes [Cp*Cl(PPh

The course of electrophilic addition to the ruthenium(II) chloro vinylidenes [Cp*Cl(PPh3)Ru(CCHR)] is influenced by the steric properties of the electrophile and ruthenium complex. Thus, H+ selectively adds to Cβ of the vinylidene ligand to yield th

Os(H)(3)ClL(2) (L = P(i)Pr(3) or P(t)Bu(2)Me) are shown to be useful "precursors" to "OsHClL(2)", which react with vinyl ethers to form first an eta(2)-olefin adduct and then isomerize to the carbenes, OsHCl[CMe(OR)]L(2). Subsequent R- and L-dependen
