Summary:Benzyltitanium chlorides and iodides were prepared by interaction of tribenzyltitanium with HCl and iodine in aromatic hydrocarbon media. The compounds are stable at temperatures below −30°C. Heating to room temperature induces quantitative disproportionation into an equimolecular mixture of Ti II and Ti IV compounds. The composition of the disproportionation products was studied. Small amounts of dienes or organoaluminium compounds were found to completely suppress the process of disproportionation; complex formation of organotitanium compounds with organoaluminium ones was investigated. A direct synthesis of TiR 3 compounds from TiCl 3 and the corresponding alkyllithiums was performed at low temperatures.
