ZIRCONIUM-BORANE COMPLEX AND METHOD FOR PRODUCING SILOXANES USING SUCH COMPLEX

摘要

Disclosed are a novel zirconium-borane complex and a method for producing the same. Also disclosed is a method for producing a commercially useful siloxanes and methane from a hydrosilane and carbon dioxide under mild conditions by using such a zirconium-borane complex catalyst. Specifically disclosed is a zirconium-borane complex represented by the following general formula (I). [Zr(R)(L)]<SUP>+</SUP>·[B(R)(C<SUB>6</SUB>F<SUB>5</SUB>)<SUB>3</SUB>]<SUP>-</SUP> (I) (In the formula, L represents a bidentate or tridentate ligand, and R represents an alkyl group or an aralkyl group.) Also specifically disclosed is a method for producing siloxanes and methane from a hydrosilane and carbon dioxide by using such a zirconium-borane complex as a catalyst.
