| Outline of Final Research Achievements |
Tetracyanocyclopentadienides having chiral binaphthyl auxiliaries has been developed as a new class of asymmetric superacid conjugate bases. The sodium tetracyanocyclopentadienides had a catalytic activity for a Mukaiyama aldol reaction and an addition reaction on acyl isoquinolinium salts, in which the reaction products had a few enantiomeric excess. In the chiral anions having an ester linker, two rotamers around C(Ar)-O bond in an aryl ester were observed at room temperature, that is a rare phenomenon for aryl esters. The rotation barriers were measured with a line-shape analysis on VT-NMR.
