Provided are a saturated N-heterocyclic carbene-ligand metal complex derivative, a method for preparing the same, and a method for preparing a silane compound by hydrosilylation using the same as a catalyst. To describe in more detail, the metal complex derivative has a saturated N-heterocyclic carbene derivative and an olefin ligand at the same time. A silane compound is prepared by hydrosilylation in the presence of the metal complex derivative as a catalyst. The provided metal complex derivative of the present invention has superior stability during hydrosilylation reaction and is capable of effectively performing the hydrosilylation reaction at low temperature even with small quantity. Further, a product with superior regioselectivity may be obtained. In addition, after the hydrosilylation reaction is completed, the metal complex derivative may be recovered and recycled.

Isolated pentacoordinate alkoxy-substituted alkenylsilicates, are readily prepared by mixing alkenyltrialkoxysilane, catechol and triethylamine at room temperature.Cross-coupling reactions of these alkenylsilicates with organic halides or triflates are catalyzed by a palladium complex and proceed very smoothly and cleanly to give the corresponding alkenes.The cross-coupling reactions could be also attained by a one pot operation without isolation of pentacoordinate organosilicates.The mechanism of this cross-coupling reaction is also described here. alkoxy-substituted alkenylsilicate / pentacoordinate silicate / cross-coupling / palladium catalyst / aryl halide / aryl triflate / styrene derivative / 1,3-diene
