Group 4 metal and vanadium bis(phenolato) complexes : synthesis, structure and olefin polymerisation activity
… to obtain a enantiomerically pure [Ti{OSSO}X2] polymerisation catalyst and to use it to determine at what degree of polymerisation a polystyrene chain becomes cryptochiral. The resolution of the Delta and Lambda enantiomers of a [Ti{2,2’-(OC6H2-6-tBu-4-Me)2SC2H4S}X2] was attempted via chiral …
