The resulting dark emerald green solution is filtered and the filtrate is concentrated to near dryness in vacuum. Diethyl ether (40 mL) is added and the solution is vigorously stirred to cause precipitation of the dark green molybdenum complex. The solution is filtered and the solid washed with two 5-mL portions of diethyl ether. The precipitate is dried in vacuum (10" 3 torr, 25 °C) to afford 3.36 g (90%) of dark emerald green cis-tetrakis(acetonitrile)-dinitrosylmolybdenum(II) bis[tetrafluoroborate(l —)]. [Pg.132]

Despite this they should be considered as possible alternatives in cases where more familiar methods fail. Amongst this group of activators are p-toluenesulfonyl chloride, tiifluoromethanesulfonic anhy-dride,silver tetrafluoroborate, molybdenum oxide, phosphorous pentoxide, trichloromethyl chloroformate, 2-fluoro-l-methylpyridiniumsulfonate, chlorosulfonyl isocyanate, antimony penta-chloride (for which an X-ray structure of the DMSO-SbCb conqilex was obtained) and phenyl dichlo-rophosphate. ...

Although Able et al. (2, 8) had originally set out to prepare 7r-cyclo-heptatrienyl complexes of metals, the cycloheptatriene complexes they actually obtained served as key intermediates in forming the former complexes. In 1958 Dauben and Honnen (61) reported that cycloheptatriene-molybdenum tricarbonyl reacted with triphenylmethyl tetrafluoroborate in methylene chloride solution with abstraction of hydride ion from the molybdenum complex. The reaction products, obtained in nearly quantitative yields, were triphenylmethane and the 7r-cycloheptatrienyl complex [(7r-C7H7)Mo(CO)3]+BF4 . [Pg.513]

Many of these complexes were purified by chromatography. The pure compounds are sensitive towards atmospheric oxygen. The bare tellurium atoms in these complexes can be protonated alkylated with methyl iodide, methyl lithium triethyloxonium tetrafluoroborate or methyl trifluoromethylsulfonate and reacted with diazoalkanes to produce complexes with coordinated telluroformaldehyde or telluroacetone. The anion [O = MoTeJ combined with dimethyl acetylenedicarboxylate to produce a tellurolate-containing molybdenum compound ... [Pg.68]

EPh3 (E = P, As, Sb, Bi) was also coordinated to a molybdenum carbonyl. This ionic complex was formed by treatment of the [CpMo(CO)3]2 dimer with ferricenium tetrafluoroborate in the presence of EPh3 (E = P, As, Sb, Bi) and Ph2P(CH2)PPh2, where the Mo—Mo bond of the dimer is cleaved in a photochemical reaction . Similarly, the highly reactive tributyl bismuth can be coordinated to group 6 metal carbonyls in a photochemical reaction (equation 38) . [Pg.352]
