Abstract Reaction of TiCl 3 (THF) 3 with 3 equivalents of LiOSi(O t Bu) 3 produces the Ti(III) siloxide Ti[OSi(O t Bu) 3 ] 3 (THF) 2 (1), and a 1:4 ratio of the same reagents gives {LiTi[OSi(O t Bu) 3 ] 4 } x . Upon heating to 95 °C, compound 1 converts via THF ring-opening to [( t BuO) 3 SiO] 3 TiO(CH 2 ) 4 Ti[OSi(O t Bu) 3 ] 3 . The pyridine adduct Ti[OSi(O t Bu) 3 ] 3 (pyr) 2 , and polymeric {Ti[OSi(O t Bu) 3 ] 3 (4,4’-bipyridine)}n, are also described. Electronic spectra for the Ti[OSi (O t Bu) 3 ] 3 L 2 complexes indicate D 3h symmetry, and similar results for the 4,4’-bipyridine adduct suggest a linear polymeric structure.
