A fluorine- and trimethylsilyl-containing phenoxy-imine titanium complex was synthesized and the structure was determined by an X-ray analysis. The complex on activation with MAO initiates highly controlled syndiospecific living propylene polymerization to form extremely high Tm syndiotactic polypropylenes (Mw/Mn = 1.05-1.08, Tm = 156-152 °C) at 0 or 25 °C. Moreover, at 50 °C, the complex afforded monodisperse syndiotactic polypropylene with very high Tm's of 149, 150 °C. In contrast, complexes having a t-Bu group instead of the silyl group provided lower tacticity polymers with much lower Tm's. In addition, we revealed the substituent effect that plays a key role for the highly controlled syndiospecific polymerization displayed by the catalyst. Copyright

A crystal structure analysis confirms the appropriateness of pentafluorophenyl salicylamine (1a) as a-acceptor for anion-interactions. Crystals of 1aHCl show that the OH-group fixes the anion in a η2-type binding motif above the electron-defici
BF3-promoted cyclization reaction of imines and salicylaldehyde with silyl enol ethers: unexpected formation of dioxaspiro compounds
Xin, Yong,Jiang, Huiling,Zhao, Jingwei,Zhu, Shizheng
, p. 9315 - 9319 (2008/12/21)
Unexpected spiro cyclic products were formed from the reaction of imines and salicylaldehyde with silyl enol ethers in the presence of BF3·OEt2. Different kinds of dioxaspiro products were afforded depending on the nature of starting
SYNTHESIS OF POLYFLUORODIBENZOXAZEPINES BY CYCLIZATION OF POLYFLUORINATED o-HYDROXYBENZYLIDENANILINES
Petrenko, N.I.,Kozlova, M. M.,Gerasimova, T. N.
, p. 93 - 98 (2007/10/02)
Thermolysis of polyfluorinated o-hydroxybenzylidenanilines leads to cyclization via intermolecular dehydrofluorination.This reaction affords a convenient method for the preparation of hitherto unknown polyfluorodibenzoxazepines.
