    • While a change of wrapping tendency of the salalen ligands upon formation of the cationic active species is not excluded, the high activity (consistent with a cis relationship between active sites), and the very high stereoregularity (consistent with non-averaging of tacticities, see below) both support the preservation of the fac-mer wrapping.
