Anwendung

Suitable as a hydrogenation catalyst for aromatic, olefin, nitrile and nitro group reductions.
Used as reducing agent for hydrogenation of organic compounds, e.g. hydrogenation of nitriles to amines, reduction of aromatic groups to the corresponding saturated compounds, hydrogenation reaction of β-keto esters, rreduction of amination, and also used as 3-alkylation of oxindole with alcohol, and Ullman-type cross coupling, and dehalogenation reactions.
