Development on synthesis of penta- and hexa-coordinated silicon intermediates directly from SiO2 as starting material in low temperature

The synthesis of hexa-coordinated silicon chelated with catechol from SiO_2 and catechol as starting material, and the synthesis of penta- and hexa-coordinated silicon intermediates from SiO_2 and glycol as starting materials were discussed. As functional intermediates, coordinate silicon complexes could be changed into many kinds of organosilicon compounds or silicon-containing monomers by a serial of chemical reactions. The high activity penta- and hexa-coordinated silicon could be used as electrical conducting materials, silicon/organic hybrid materials, molecular sieve and zeolite and silicon containing polymers.
