Abstract : Tetrakis(triethylsilyloxy)titanium, Ti(OSiEt3)4, was hydrolyzed under controlled conditions in dioxane at 60C. The soluble initial products (TiOx(OSiEt3)(4-2x))n, with x = 0.1-0.5, underwent disproportionation when heated at 65C under high vacuum to give Ti(OSiEt3)4 and products with values of x in the range 0.4-1.4. Molecular weights were determined by cryoscopy in cyclohexane, and the linear dependence of 1/n on x was used as a basis for structural proposals. The results are compared with those obtained previously for the initial products of hydrolysis. (Author)
