## Abstract After modification of silica with benzoyl chloride (BC) to obtain BCβmodified SiO~2~ (BCβSiO~2~), BCβSiO~2~/TiCl~4~ and BCβSiO~2~/BEM/TiCl~4~ catalysts were prepared by treating the BCβSiO~2~ with TiCl~4~ directly or with butylethylmagnesium (BEM) followed by TiCl~4~, respectively. Duri
Reactions of bis(cyclopentadienyl)titanium dichloride, bis(cyclopentadienyl)zirconium dichloride, and bis(cyclopentadienyl)hafnium dichloride with premodified silica gel surfaces were studied. The silica gel surface was pretreated to selectively eliminate nonhydrogen bonded silanols, hydrogen bonded
