Zirconocene silanolate complexes and their heterogeneous siliceous analogues as catalysts for phenylsilane dehydropolymerization
Original language description
The efficient catalytic dehydropolymerization of phenylsilane by homogeneous zirconocene bissilanolates ([{(c-C5H9)7Si8O12O}2Zr(?5-C5H5)2] (1a); [{(c-C5H9)7Si8O12O}2Zr(?5-C5H4Bu)2] (1b) [{(c-C5H9)7Si7O9(OSiMe3)O2}Zr(?5-C5H5)2] (4); [{(Me3CO)3SiO}2Zr(?5-C5H5)2] (5)) and chlorosilanolates ([{(c-C5H9)7Si8O12O}ZrCl(?5-C5H4Bu)2] (2); ([{(c-C5H9)7Si7O9O3}Zr2Cl(?5-C5H5)4] (3a); [{(c-C5H9)7Si7O9O3}Zr2Cl(?5-C5H4Bu)4] (3b)) has been demonstrated. The presence of at least one silanol ligand in the zirconocene moiety was found essential for high catalytic performance. Solid state structure of complex 1a was determined by single crystal X-ray diffraction analysis. A series of nine zirconocene-siliceous catalysts were prepared by grafting of zirconocene moiety ontosilica using three general methods: (a) reaction of [(?5-C5H5)2ZrCl2] with silica in the presence of NEt3; (b) reaction of [(?5-C5H5)2ZrMe2] with silica; (c) reaction of solely [(?5-C5H5)2ZrCl2] with silica. Supported catalysts were chara
