Dichlorodiacetatotitanium(Ⅳ) dissolves in alcohols with chemical reaction. Such solvolytic reaction of TiCl2(OAc)2 with various alcohols has been studied by means of solution NMR spectroscopy and chemical analysis of the isolated products. The reaction of TiCl2(OAc)2 with primary alcohols has shown to be a quantitative two-step ligand substitution process as shown in the following: TiCl2(OAc)2 + ROH → TiCl2(OR) + AcOH TiCl2(OAc)(OR) + ROH → TiCl2(OR)2 + AcOH The molecular form initially soluble in organic solvents has been found to be the monosubstituted species TiCl2(OAc)(OR). Alcoholysis with t-butyl alcohol has shown remarkable differences. When the mole ratio of t-butyl alcohol to TiCl2(OAc)2 is less than 1/2, the following reaction is dominant. TiCl2(OAc)2 + t-ButOH → TiCl(OH)(OAc)2 + tButCl However, at higher mole ratio another substitution process resembling the first step reaction with primary alcohols is competitively accompanied. The reaction with t-butyl alcohol also differs from that with primary alcohols in that only one either of the two chloro-or acetato-ligands in TiCl2(OAc)2 is subjected to substitution.
