English abstract:
When Ti(OiPr)4 was reacted with increasing proportions of methacrylic acid (McOH), the compounds Ti2(OiPr)6(OMc)2(iPrOH), Ti6O4(OiPr)8(OMc)8, Ti9O8(OiPr)4(OMc)16, and Ti8O8(OMc)16 were obtained in sequence. This allowed conclusions on the relative ratio of substitution and hydrolysis reactions, the latter being due to ester formation between the acid and cleaved alcohol. This ratio is also influenced by the reaction temperature, since Ti4O2(OiPr)6(OMc)6 was formed instead of Ti6O4(Oi-Pr)8(OMc)8 at lower temperature with the same precursorratio.
