Procedure

The catalyst was also prepared from rhodium trichloride by the addition of one gram hydrated rhodium trichloride to 200 milliliters methanol and 20 milliliters water. To the mixture was added 7 grams of triphenylphosphine and the system was then refluxed for 30 minutes under an atmosphere containing equal molar quantities of carbon monoxide and hydrogen. Thereafer 2 grams of sodium borohydride dissolved in 50 milliliters of methanol were added and the system was refluxed for another 30 minutes, then cooled and filtered. The yellow solid was washed thoroughly with metahnol and air dried to obtain 3.49 grams of tris(triphenylphosphine rhodium carbonyl hydride.
