Pentamethylcyclopentadienyl-indium(I) and -Indium(III) Compounds--Syntheses, Reactivities and X-Ray Diffraction and Electron Diffraction Studies of In(C5Me5)

摘要

The golden yellow compound In(C5Me5) has been prepared in only 62% yield from InC1 and Li(C5Me5) in diethyl ether and fully characterized according to its physical and solubility properties, its reaction with dilute aqueous HC1, a cryoscopic molecular weight study in cyclohexane, IR and 1H NMR spectroscopic properties, a single crystal X ray diffraction study and a gas phase electron diffraction study. The other products of this reaction have been identified as In(C5Me5)2C1, indium metal and (C5Me5)2 in 5.0, 21 and 2.5% yields, respectively. Keywords: Indium, Cyclopentadienyl-indium(I) chemistry, Pentamethylcyclopentadienyl compounds, X ray structural study, Electron diffraction study. (MJM)
