Title: Catalysts For Hydrogenation And Hydrosilylation Methods Of Making And Using The Same

Abstract

A compound is provided including an organometallic complex represented by the formula I: wherein M is an atom of molybdenum or tangsten, Cp is substituted or unsubstituted cyclopentadienyl radical represented by the formula [C.sub.5 Q.sup.1 Q.sup.2 Q.sup.3 Q.sup.4 Q.sup.5 ], wherein Q.sup.1 to Q.sup.5 are independently selected from the group consisting of H radical, C.sub.1-20 hydrocarbyl radical, substituted hydrocarbyl radical, halogen radical, halogen-substituted hydrocarbyl radical, --OR, --C(O)R', --CO.sub.2 R', --SiR'.sub.3 and --NR'R", wherein R' and R" are independently selected from the group consisting of H radical, C.sub.1-20 hydrocarbyl radical, halogen radical, and halogen-substituted hydrocarbyl radical, wherein said Q.sup.1 to Q.sup.5 radicals are optionally linked to each other to form a stable bridging group, NHC is any N-heterocyclic carbene ligand, L is either any neutral electron donor ligand, wherein k is a number from 0 to 1 or L is an anionic ligand wherein k is 2, and A.sup.- is an anion. Processes using the organometallic complex as catalyst for hydrogenation of aldehydes and ketones are provided. Processes using the organometallic complex as catalyst for the hydrosilylation of aldehydes, ketones and esters are also provided.
