摘要

When the product of the reaction of 2,6-di-tert.-butylphenol with TiCl _4 in a 3:1 ratio is treated with Na[HBEt_3], the isolated product is not (2,6-tert.-Bu_2C_6H_3O) _3Ti(HBEt_3) but the isomerized ester (2,4-tert.-Bu _2C_6H_3O)_4Ti with molecular S _4 symmetry. This rearrangement of the R substituents does notoccur upon reacting 2,6-diisopropylphenol with TiCl_4 and Na[HBEt _3]. An unexpected result is also observed for the product of the reaction of tris(2,6-diisopropylphenolato)titanium(IV) chloride with lithium bis(pentafluorophenolato)dihydridoborate. The isolated product proved to be dimeric tris(pentafluorophenolato)(2,6-diisopropylphenolato)titanium(IV) with two bridging pentafluorophenolato groups generating pentacoordinated Ti atoms.
