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 TiII and TiIV compounds. The composition of the disproportionation products was studied. Small amounts of dienes
