Outline of Final Research Achievements

The purpose of the research is to replace noble-metal-catalysts for the reduction of unsaturated bonds into base-metal-catalysts. Iron complex 1, which bears Fe-Si bonds, catalyzed hydrogenation of alkenes under mild condition (1 atm of H2 at ambient temperature). Theoretical studies revealed that H-H bond is activated not on the iron center but with the assist of Fe-Si bond to afford Fe-H and Si-H bond with lower energy barrier. This system could be applied into other metals by synthesizing Ru analogues. Finally, we achieved to develop highly efficient Fe catalysts for the hydrogenation of sterically-hindered tetrasubstituted alkenes.
