Several monosubstituted derivatives have been made in a similar manner, except that a unidentate ligand is used in place of the carbon monoxide, namely NH3, N2H4 (88) C2H4 (75) PPh3, AsPh3, CH3CN (231). Alternatively, substituted monooleiin derivatives have been synthesized by protonation of the metal a-allyl 7r-cyclopentadienyl tricarbonyl (55, 112). [Pg.136]

Dicarbonyl cationic derivatives, [CpM(CO)2L2]+, containing Lewis bases, L, have been obtained in a variety of ways. Direct halide displacement from the 77-cyclopentadienyl tricarbonyl halides has been reported for... [Pg.136]

The methylation of (/(-tellurido)bis[7t5-cyclopentadienyl(tricarbonyl)]chromium by methyl trifluoromethanesulfonate in diethyl ether at 20° produced a methyltelluro-bridged complex that was isolated as the hexafluorophosphatc2. The red-brown solid forms needles that are stable in air for a short time only. [Pg.215]

The cyclopentadienyl tricarbonyl molybdenum and tungsten dimers also react with [(7r-Ph4C4)PdX2]2 (X = Cl, Br) complexes but by transfer of the tetraphenylcyclobutadiene group 182). [Pg.390]

In solution, the cyclopentadienyl tricarbonyl dimers [CpMo(CO)3]2 and [CpW(CO)3]2 react to form the heterobimetallic complex Cp(CO)3Mo-W(CO)3Cp. However, the reaction does not go to completion a mixture results in which the [CpMo(CO)3]2 and [CpW(CO)3]2 are in equilibrium with the mixed metal compound. The abundance of the three organometallic complexes is governed statistically by the number of CpMo(CO)3 and CpW(CO)3 fragments present. If 0.00100 mmol of [CpMo(CO)3]2 and 0.00200 mmol of [CpW(CO)3]2 are dissolved in toluene until equilibrium is achieved, calculate the amounts of the three organometallic complexes in the equilibrium solution.
