Abstract: | The oxidation elimination reaction between dicarbonyl titanocene and aryltin halides was studied by means of paramagnetic resonance spectroscopy. The radical intermediates containing Ti(III) were discovered from the ESR spectra to be (Cp2TiSnArnX3-n), Cp2Ti(CO)X, and Cp2TiX, and a radical mechanism for the reaction is proposed. © 1996 John Wiley & Sons, Inc. |
