HEXARHODIUM HEXADECACARBONYL Usage And Synthesis

Chemical Properties

black crystal(s); cluster structure; used as a catalyst [COT88] [ALD94] [ALF95]

Uses

Catalyst for hydrogenation of alkenes, hydroformylations ofalkenes; reducing agent for aldehydes, ketones, and nitro groups; catalyst for carbenoid reactions of diazo compounds

Purification Methods

It slowly loses CO when heated in air, but may be regenerated by heating at 80-200o in the presence of CO at 200atmospheres pressure for 15hours, preferably in the presence of Cu. It forms black crystals which are insoluble in hexane. It has bands at 2073, 2026 and 1800cm-1 in the IR.
