(BICYCLO[2.2.1]HEPTA-2,5-DIENE)CHLORORHODIUM(I) DIMER Chemical Properties,Usage,Production

Chemical Properties

mustard yellow crystals

Uses

Di-μ-chlorobis(norbornadiene)dirhodium(I) is used as catalysts in olefin hydroformylation, olefin hydrogenation and olefin isomerization

Preparation

Bis(bicyclo[2.2.1]hepta-2,5- diene)dichlorodirhodium is prepared by reacting rhodium(III) Chloride and bicyclo[2.2.1]hepta-2,5-diene in aq ethanol, when shaken for 2 days, give a yellow deposit.

reaction suitability

core: rhodium
reagent type: catalyst

Purification Methods

It recrystallises from hot CHCl3/pet ether as fine crystals soluble in CHCl3 and *C6H6 but is almost insoluble in Et2O or pet ether. [Abel et al. J Chem Soc 3178 1959.]
