Under (not so much) pressure: A general method for the hydrogenation of tertiary and secondary amides to amines with excellent selectivity using a bimetallic Pd–Re catalyst has been developed. The reaction proceeds under low pressure and comparatively low temperature. This method provides organic chemists with a simple and reliable tool for the synthesis of amines.

(EN) A method for increasing the water-solubility of indomethacin or piroxicam by forming a complex product from the reaction between the indomethacin or piroxicam and an aqueous solution of a solid quaternized organic compound. The solubility of the indomethacin or piroxicam can be increased at least 25-fold, and the complex formed is highly stable at ambient conditions.(FR) Le procédé décrit, qui sert à augmenter l'hydrosolubilité de l'indométhacine ou du piroxicame, consiste à former un produit complexe à partir de la réaction entre l'indométhacine ou le piroxicame et une solution aqueuse d'un composé organique quaternisé solide. La solubilité de l'indométhacine ou du piroxicame peut être augmentée d'au moins 25 fois et le complexe formé se révèle hautement stable dans des conditions ambiantes.
