摘要: The invention relates to a method for carrying out CC-coupling reactions, in particular a Heck and Suzuki reaction, in the presence of supported palladium as the catalyst and a base in a monophase or multiphase solvent mixture. According to said method, palladium detaches itself from the support in a characteristic manner, is redeposited after the reaction and the quantity of palladium not deposited after the reaction is significantly lower than 5000 ppm, in relation to the palladium used.

摘要: The present invention focuses on a process for the hydrogenation of aromatic or heteroaromatic compounds and in particular on the ring hydrogenation of compounds having the formula (I). Aromatic amino acids and amino alcohols can be successfully ring-hydrogenated using a platinum-rhodium mixed catalyst. The products can be used inter alia as mimetics in bioactive peptide active ingredients.
