ABSTRACT:
The selective addition of a compound having an activated carbon atom onto the carbon atom in the 4-position of a buta-1,3-diene carrying a hydrocarbon substituent on the carbon atom in the 2-position is achieved by reacting the compound having the activated carbon atom with the buta-1,3-diene carrying the hydrocarbon substituent in water or in an aqueous-alcoholic mixture in the presence of a catalyst which consists of at least one water-soluble phosphine and at least one rhodium compound, the catalyst being in solution in the water or aqueous alcoholic mixture. The products obtained are useful as precursors of intermediates for the synthesis of vitamins and perfumes.
