Titanium tert-butoxide (Ti(OC(CH3)3)4; Ti(OtBu)4) was chemically modified with catechol (C6H4(OH)2) and hydrolysis and condensation behavior of a resultant modified alkoxide was studied. Spectroscopic results revealed that the reaction between titanium tert-butoxide and catechol resulted in the formation of catecholate groups (C6H4O22-) bound to titanium and corresponding release of tert-butanol. The mass spectrometry and cryoscopy indicated that main species was a dimer [(C6H4O2)2Ti2 (OtBu)4]. The hydrolysis of the modified alkoxide in the system with Ti:tetrahydrofuran (THF):H2O = 1:10:x (x = 0.5-10) resulted in the partial hydrolysis, and all the hydrolyzed products after the drying under reduced pressure were soluble in THF and chloroform.
