Abstract

A series of chiral dimeric ligands 1A–C, 2A–B, 3A–B and 4A derived from (S)/(R) 1, 1′-bi (2- naphthol)-bis-aldehyde/piperazine-bis-aldehyde and various aminoalcohols viz.,(1 R, 2 S)- (−)-2-aminodiphenylethanol,(1 S, 2 R)-(−)-2-aminodiphenylethanol,(1 R, 2 S)-1-amino-2, 3- dihydro-1 H-inden-2-ol and (R)-valinol were synthesized. In situ generated complexes 1A–C– , 2A–B–, 3A–B–, 4A–Cu (II)/Cu (I) of dimeric chiral ligands with different copper salts were ...
