Binucleating Ligands:  Synthesis of Acyclic Achiral and Chiral Schiff Base−Pyridine and Schiff Base−Phosphine Ligands

The Journal of Organic Chemistry, 1996
5-tert-Butyl-3-(2‘-pyridyl)salicyaldehyde and 5-tert-butyl-3-(diphenylphosphino)salicyaldehyde were synthesized from 4-tert-butylphenol in good overall yields. Condensation of the salicyaldehydes with 2,3-diamino-2,3-dimethylbutane afforded the desired dinucleating Schiff base−pyridine and Schiff base−phosphine ligands, respectively. 5-tert-Butyl-3-(2‘-
