| Abstract: | Tetra-t-butylchromium was prepared from CrCl3·3THF and t-butyllithium in pentane by a disproportionation reaction or from tetra-t-butoxychromium and t-butyllithium. It was isolated by sublimation and characterized by ESR, UV, visible and IR spectra. The following compounds were not isolated but characterized in solution by their ESR spectra: tetramethylchromium, tetraisopropylchromium, tetra-sec-butylchromium, tetra-n-butylchromium, tetra-3-pentylchromium and tetrakis(cyclohexylmethyl)chromium. |
