Popis: | New chiral metal salen complexes substituted in the 3 position with bulky silyl groups (TMS, TBDMS) have been synthesized. Although some of these complexes catalyzed the epoxidation of unfunctionalized olefins in moderate to high ee's, they catalyzed the aziridination of cis-β-methylstyrene without any asymmetric induction. |
