The present invention provides a method for preparing rhodium (III) 2-ethylhexanoate solutions which supplies the reaction product with higher space yield, as well as lower sodium and chloride ion content. An aqueous solution of an alkali salt of 2-ethylhexanoate is thereby initially converted with a rhodium (III) precursor. The rhodium (III) precursor is selected from rhodium (III) chloride solution, rhodium (III) chloride hydrate, and rhodium (III) nitrate. The mixture is heated for several hours. After cooling to room temperature, the rhodium (III) 2-ethylhexanoate formed is extracted from the aqueous solution with an alcohol that is immiscible in water or a carboxylic acid that is immiscible in water, and optionally washed with aqueous mineral acid. The rhodium (III) 2-ethylhexanoate solution obtainable in this way may be used directly as catalyst in hydroformylation reactions.

The invention relates to a method for the cost-effective and environmentally friendly production of alkyl indium sesquichloride in high yield and with high selectivity and purity. The alkyl indium sesquichloride produced according to the invention is particularly suitable, also as a result of the high purity and yield, for the production, on demand, of indium-containing precursors in high yield and with high selectivity and purity. As a result of the high purity, the indium-containing precursors that can be produced are particularly suitable for metal organic chemical vapour deposition (MOCVD) or metal organic vapour phase epitaxy (MOVPE). The novel method according to the invention is characterised by the improved execution of the method, in particular a rapid process control. Owing to targeted and extensive use of raw materials that are cost-effective and have a low environmental impact, the method is also suitable for use on an industrial scale.
