The present invention is directed to a process for the preparation of the reagent dimethyl titanocene (Cp2Ti(CH3)2) from titanocene dichloride (Cp2TiCl2) and a methyl magnesium halide, in particular, methyl magnesium chloride (CH3MgCl). The instant process provides the desired reagent in a manner which is generally less hazardous and more economical than previous methods.
Procédé d'élaboration du réactif diméthyle titanocène (Cp¿2?Ti(CH¿3?)¿2?) à partir de dichlorure de titanocène (Cp¿2?TiCl¿2?) et d'un halogénure de méthyle magnésium, en particulier d'un chlorure de méthyle magnésium (CH¿3?MgCl). Ce procédé instantané permet d'obtenir le réactif désiré d'une manière qui est essentiellement moins dangereuse et plus économique que selon les procédés actuels.
