Synthesis, structure and redox properties of bis(cyclopentadienyl)dithiolene complexes of molybdenum and tungsten.
The compounds [Cp(2)M(S(2)C(2)(H)R)] (M = Mo or W; R = phenyl, pyridin-2-yl, pyridin-3-yl, pyridin-4-yl or quinoxalin-2-yl) and [Cp(2)Mo(S(2)C(2)(Me)(pyridin-2-yl)] have been prepared by a facile and general route for the synthesis of dithiolene complexes, viz. the reaction of [Cp(2)MCl(2)] (M = Mo or W) with the dithiolene pro-ligand generated by reacting the corresponding 4-(R)-1,3-dithiol-2-...
متن کاملSynthesis and molecular structure of (g-pentamethyl-cyclopentadienyl) (g-cyclopentadienyl) hexacarbonyl molybdenum tungsten
The metathesis reaction of Cp*(CO)3MoBr and NaW(CO)3Cp produced Cp*(CO)3Mo–W(CO)3Cp (1), featuring an unsupported Mo–W bond. Exposure of solutions of 1 to light leads to the quantitative formation of the corresponding homometallic dimers. In the solid state, the title complex exhibits an anti-arrangement of the g-cyclopentadienyl and the g-pentamethylcyclopentadienyl ligands and six terminal ca...
متن کاملChelated h-cyclopentadienyl-h-ethyl complexes of molybdenum and tungsten; molecular structure of W(h-C5H4CH2-h-CH2)(CO)3
Molybdenum and tungsten complexes M(h-C5H4CH2-h-CH2)(CO)3 (M=Mo, W) containing the bidentate ethyl-functionalized cyclopentadienyl ligand C5H4CH2CH2 have been synthesized by the reaction of spiro[2.4]hepta-4,6-diene with M(CO)3L3 (M=Mo; L3=1,3,5-C6H3Me3; M=W; L=NCMe). Reaction of the more stable tungsten complex with C6H5ICl2 and HBF4 gave complexes of the type W(h-C5H4CH2CH2Cl)(CO)3Cl, W(h-C5H...
متن کاملFundamental Studies of Molybdenum and Tungsten Methylidene and Metallacyclobutane Complexes
Addition of ethylene to Mo(NAr)(CHCMe2Ph)(OHIPT)(Pyr) (NAr = N-2,6-i-Pr2C6H3, OHIPT = O-2,6-(2,4,6-i-Pr3C6H2)2C6H3, Pyr = NC4H4) led to the trigonal bipyramidal metallacyclobutane complex, Mo(NAr)(C3H6)(OHIPT)(Pyr), in which the imido and aryloxide ligands occupy axial positions. Mo(NAr)(C3H6)(OHIPT)(Pyr) loses ethylene to give isolable Mo(NAr)(CH2)(OHIPT)(Pyr). W(NAr)(CH2)(OTPP)(Me2Pyr) (OTPP ...
متن کاملPhosphaalkenyl germylenes and their gold, tungsten and molybdenum complexes.
The new bis(phosphaalkenyl) germanium(II) compound (NHC)Ge(CCl=PMes*)(2) reacts with L(2)M(CO)(4) (M = Mo, W) to give bidentate complexes with an unexpected coordinating behaviour involving the Ge(II) centre and one phosphorus atom, and with AuI or Me(2)SAuCl to afford the monodentate complexes coordinated at the germanium(II) atom.
