Stereoselective Synthesis of Alicylic Amines

Abstract

The hydrogenation 4-alkylanilines over Rh/ silica catalysts display an antipathetic particle size effect suggesting that the active site is a terrace face. The effect of the solvent on product cis:trans ratio was related to polar solvents stabilising an imine intermediate. The products inhibited the reaction due to their increased basicity which allowed a strong metal-nitrogen interaction.

The effect of impurities on the steam reforming of ethanol over ruthenium/alumina

“…Therefore in the light of these results we propose that acetone and propyl amine induce rapid deactivation of the metal function during ESR and that the residual activity observed is due to the alumina support. Amines are known to be poisons for precious metal catalysts in a variety of reactions [27][28][29][30] due to the strong interaction Catalysis Science & Technology Paper between the nitrogen lone pair and the metal. However in this case the deactivation of the metal is masked by the conversion associated with the alumina.…”
