Synthesis and Characterization of Hydrido Carbonyl Molybdenum and Tungsten PNP Pincer Complexes
In the present study the Mo(0) and W(0) complexes [M(PNP)(CO)3] as well as seven-coordinate cationic hydridocarbonyl Mo(II) and W(II) complexes of the type [M(PNP)(CO)3H]+, featuring PNP pincer ligands based on 2,6-diaminopyridine, have been prepared and fully characterized. The synthesis of Mo(0) complexes [Mo(PNP)(CO)3] was accomplished by treatment of [Mo(CO)3(CH3CN)3] with the respective PN...
متن کاملPhotochemistry of Carbonyl Complexes
The photosensitivity of metal carbonyls has been known almost as long as the class of coordination compounds itself. Among no other group of inorganic compounds may one find so many light-sensitive materials. Hence photochemical reactions of metal carbonyls have found wide applications for synthetic purposes. However, whereas much research has been done to understand the thermal reactions," the...
متن کاملCarbonyl(diphenylcyclopentadienyl)- und Carbonyl(tetraphenylcyclopentadienyl)rhodium(I) Komplexe Carbonyl(diphenylcyclopentadienyl)- and Carbonyl(tetraphenylcyclopentadienyl)rhodium(I) Complexes
[Rh(CO)2Cl] 2 reacts with 1,3-diphenylcyclopentadienyl sodium or tetraphenylcyclopentadienyl sodium with formation of (l,3-P h2C5H3)Rh(CO ) 2 (1) or (C5HPh4)Rh(CO )2 (2), respectively. The reaction of 1 or 2 with PPh3 yields the corresponding carbonyl(cyclopentadienyl)(triphenylphosphane)rhodium complexes (l,3 -P h 2C5H3)Rh(CO)(PPh3) (3) or (C5HPh4)Rh(CO)(PPh3) (4). The 'H and ' C reported and ...
متن کاملElectrochemical reactions of pincer rhodium(I) complexes
The electrochemical properties of the (PCP)Rh(H2) (1-H2, PCP 1⁄4 k-C6H3e2,6-(CH2P(Bu2)) complex was examined by cyclic voltammetry in acetonitrile (MeCN), dimethylsulfoxide (DMSO) and 1,2difluorobenzene (1,2-DFB). Upon oxidation in weakly or non-coordinating media such as 0.05 M NaBAr24 in 1,2-difluorobenzene, simple one electron oxidation to [(PCP)RhII(H2)]þ is observed. Conversely, in coordin...
متن کاملCSC-pincer versus pseudo-pincer complexes of palladium(II): a comparative study on complexation and catalytic activities of NHC complexes.
Three thioether bridged diimidazolium dibromides with different steric and electronic properties have been synthesized as precursors to carbene-based CSC pincer ligands. Palladation afforded CSC Pd(II) pincer complexes for bulky and electron rich ligand systems, whereas the least donating ligand led to the formation of a pseudo-pincer complex. All complexes have been fully characterized by mult...
