Methods to produce a range of new phosphine-diamine ligands from phosphino-aldehydes have been developed and a hypothesis that larger P-substituents would increase the enantioselectivity towards the (S) isomer in Ru-catalysed ketone hydrogenation of acetophenone has been examined; the successful validation of this hypothesis is further evidence that the mechanism of these catalysts involves a secondary amine assisted reduction.
