Terminal imido rhodium complexes.
Compounds of the late transition metals with M=X multiple bonds (X=CR2, NR, O) represent a synthetic challenge, partly overcome by preparative chemists, but with noticeable gaps in the second- and third-row elements. For example, there are no isolated examples of terminal imido rhodium complexes known to date. Described herein is the isolation, characterization, and some preliminary reactivity ...
متن کاملPseudotetrahedral rhodium(I) complexes.
A combination of four-electron donors, such as alkynes, with strongly donating and strong-field scorpionate ligands is appropriate to create pseudotetrahedral rhodium(I) environments, as found in [Rh(PhBP3 )(HCCPh)], which promotes HC bond activation and CC coupling reactions under very smooth conditions.
متن کاملAqueous rhodium(III) hydrides and mononuclear rhodium(II) complexes.
In aqueous solutions, as in organic solvents, rhodium hydrides display the chemistry of one of the three limiting forms, i.e. {Rh(I)+ H+}, {Rh(II)+ H.}, and {Rh(III)+ H-}. A number of intermediates and oxidation states have been generated and explored in kinetic and mechanistic studies. Monomeric macrocyclic rhodium(II) complexes, such as L(H2O)Rh2+ (L = L1 = [14]aneN4, or L2 = meso-Me6[14]aneN...
متن کاملVersatile bonding and coordination modes of ditriazolylidene ligands in rhodium(iii) and iridium(iii) complexes.
Metalation of novel ditriazolium salts containing a trimethylene (-CH2CH2CH2-) or dimethylether linker (-CH2OCH2-) was probed with different rhodium(iii) and iridium(iii) precursors. When using [MCp*Cl2]2, a transmetalation protocol via a triazolylidene silver intermediate was effective, while base-assisted metalation with MCl3via sequential deprotonation of the triazolium salt with KOtBu and a...
متن کاملC–C complexes of rhodium
In this article, the complexes [Rh(Binor-S )(PR3)][BAr4] (R iPr, Cy, C5H9) are described. A combination of x-ray crystallography, NMR spectroscopy, density functional theory, and ‘‘atoms in molecules’’ calculations unequivocally demonstrates that the complexes contain rare examples of metal C–C agostic interactions. Moreover, they are fluxional on the NMR time scale, undergoing rapid and revers...
