Cationic Molybdenum Imido Alkylidene Complexes
Addition of 1 equiv of [HNMe2Ph]BAr4 (Ar ) 3,5-(CF3)2C6H3) to Mo(NAr)(CHCMe2Ph)(Pyrrolide)2 (Pyrrolide ) parent pyrrolide (Pyr) or 2,5-dimethylpyrrolide (Me2Pyr)) species in THF produced [Mo(NAr)(CHCMe2Ph)(Pyrrolide)(THF)x]BAr4 species (x ) 2 for Me2Pyr (1b) or 3 (1a) for Pyr; Ar ) 2,6-diisopropylphenyl). [Mo(NAr)(CHCMe2Ph)(Me2Pyr)(2,4-lutidine)]BAr4 (1c) was formed upon addition of 2,4-lutidin...
متن کاملSynthesis and reversible reductive coupling of cationic, dinitrogen-derived diazoalkane complexes.
A series of cationic diazoalkane complexes [4-RC(6)H(4)C(H)NNMo(N[t-Bu]Ar)(3)][AlCl(4)], [1-R][AlCl(4)] (R = NMe(2), Me, H, Br, CN; Ar = 3,5-C(6)H(3)Me(2)) has been prepared by treatment of the N(2)-derived diazenido complex Me(3)SiNNMo(N[t-Bu]Ar)(3) with 4-RC(6)H(4)CHO and 2 equiv of AlCl(3). The structures of [1-H][AlCl(4)] and [1-NMe(2)][AlCl(4)] were determined by X-ray crystallography. The...
متن کاملBipyridine Adducts of Molybdenum Imido Alkylidene and Imido Alkylidyne Complexes.
Seven bipyridine adducts of molybdenum imido alkylidene bispyrrolide complexes of the type Mo(NR)(CHCMe(2)R')(Pyr)(2)(bipy) (1a-1g; R = 2,6-i-Pr(2)C(6)H(3) (Ar), adamantyl (Ad), 2,6-Me(2)C(6)H(3) (Ar'), 2-i-PrC(6)H(4) (Ar(iPr)), 2-ClC(6)H(4) (Ar(Cl)), 2-t-BuC(6)H(4) (Ar(t) (Bu)), and 2-MesitylC(6)H(4) (Ar(M)), respectively; R' = Me, Ph) have been prepared using three different methods. Up to th...
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 کاملThe Synthesis of Biomimetic Tungsten and Molybdenum Complexes
The synthesis of novel biornimetic molybdenum and tungsten compounds that are potential model complexes for molybdenum and tungsten oxidase enzymes is being pursued. Model complexes such as these provide a bener understanding of the basic chemistry of a metal center in an environmeot similar to that found in particular enzyme active sites. This understanding provides a good Starting point [or b...
