The X-ray crystal structure and electrochemical data of a manganese complex
[L2Mn2III(mu -O)(mu -AcO)(2)][PF6](2) with L being an enantiopure C-3-symm
etric 1,4,7-triazacyclononane derived from L-proline are compared to those
of [Me-3- TACN(2)Mn(2)(III)(mu -O)(mu -AcO)(2)][PF6](2); catalytic studies
reveal the applicability of the complex in enantioselective epoxidations.
