Description and Uses

Rhodium(III) chloride hydrate is used as a catalyst to prepare acetic acid. It is also used as a catalyst for the isomerization of alkenes, the reduction of aromatic rings, the oxidation ofalkenes, the hydration of acetylene. It is involved in the hydrosilylation of α,β-unsaturated esters to form dimethylketene trimethylsilyl acetals.
