Abstract
5-tert-Butyl-3-(2'-pyridyl)salicyaldehyde and 5-tert-butyl-3-(diphenyl phosphino)salicyaldehyde were synthesized from 4-tert-butylphenol in g ood overall yields. Condensation of the salicyaldehydes with 2,3-diami no-2,3-dimethylbutane afforded the desired dinucleating Schiff base-py ridine and Schiff base-phosphine ligands, respectively. 5-tert-Butyl-3 -(2'-pyridyl) salicyaldehyde reacted with optically active 1,2-diamino cyclohexanes to give chiral dinucleating Schiff base-pyridine ligands.
