In a collaboration between the UK, Sweden and the US, Clarke, France and Kann have found a way to produce a range of new phosphine-diamine ligands from phosphino-aldehydes. In the article, they also hypothesise that larger P-substituents would increase the enantioselectivity towards the (S) isomer in Ru-catalysed ketone hydrogenation of acetophenone.
Their investigations confirm the mechanism of operation of these important catalysts….. find out what they found it to be by reading their short communication.
