An aqueous phase process for the amination of biogenic isohexides with ammonia using Ru/C as solid catalyst is reported. The products possess great potential for the production of biogenic polyamides. From the diol substrates amino alcohols and diamines are derived as main products with significantly varying product selectivity depending on the substrates’ stereochemistry. The catalytic reaction is performed at temperatures of 140–180 °C. The Ru/C catalyst shows a high activity in the aqueous phase, which is beneficial for the transformation of the polar biogenic substrates. Despite the basic conditions, the metal leaching is negligible and the catalyst can be recycled easily in batch operation and, thus, enables further process development thanks to the mild and scalable reaction conditions.
