Syntheses and characterization of titaniosiloxane and zirconiosiloxane compounds were investigated.Titaniosiloxane and zirconiosiloxane compounds were prepared by the reaction of di-t-butoxymethoxysilanol with titanium or zirconium alkoxides.DBMS was subjected to the reaction with bis(acetylacetonato)titanium diisopropoxide and titanium tetraisopropoxide to give titaniosiloxane compounds TS12 and TS14, respectively.Titaniosiloxane compounds were isolated by distillation or sublimation.TS12 was estimated to be cis-form from its 13C NMR spectrum in CDCl3.TS14 was stable in solution, but apt to decompose after isolation.ZS12 and ZS14 were prepared by the reaction of DBMS with bis(acetylacetonato)zirconium diisopropoxide and zirconium tetraisopropoxide, respectively.The isolation of ZS12 and ZS14 by distillation or recrystallization was difficult because of decomposition and high solubility, and the formation of ZS12 and ZS14 was confirmed by 1H, 13C, and 29Si NMR and IR spectra.
