Stereocontrol mechanism in CO/p-methylstyrene copolymerisation catalysed by aryl-α-diimine Pd(II) complexes

Structural analysis of the first steps of isotactic CO/p-methylstyrene copolymerisation, catalysed by aryl-alpha-diimine Pd(II) complexes, highlights the influence of steric effects on the stereoselectivity of olefin insertion.
