The invention relates to a method for synthesizing rhodium chloride (triphenylphosphine). The method of the invention takes rhodium chloride trihydrate and triphenylphosphine with the mass ratio of 1:5 to 5 as main raw materials for synthesizing the rhodium chloride (triphenylphosphine) rhodium in an alcohol-water mixed solvent under the condition of microwave radiation, wherein, the microwave radiation power ranges from 100 to 1000W, microwave reaction time lasts for 5 to 30 minutes, and the reaction formula is: RhCl3.3H2O + 4PPh3-RhCl(PPh3) + PPh3Cl2 in the presence of MW. The method has the advantages of high heating speed, short reaction time, high reaction yield, simple and convenient reaction operation, simple treatment after reaction and simplified process flow, and the like.
Description
Technical field The invention relates to a microwave synthesis method of tris(triphenylphosphine) rhodium chloride. Background technique Tris(triphenylphosphine) rhodium chloride is the first coordination compound discovered in 1965 by G. Wilkinson, a Nobel Prize winner in chemistry, as a hydrogenation catalyst in a homogeneous solution. As an unsaturated organic molecular hydrogenation catalyst, it can carry out catalytic hydrogenation, aldehyde decarbonylation, partial substitution of propylene and other reactions under mild conditions, and is widely used in olefin selective hydrogenation, carbonylation, and formylation reactions. The traditional process for synthesizing tris(triphenylphosphine) rhodium chloride was reported by Osborn, J. et al. (Inorg, Synth. 10, 67) in 1967, and there are disadvantages such as large solvent consumption and low yield. The Dutch patent NL6602062A reported the preparation of a series of organophosphine ligand rhodium chloride compounds, and t...
