Synthesis of dinucleating phenanthroline-based ligands
摘要:
The phenolic bridged dinucleating phenanthroline-pyridine, phenanthroline-phosphine, phenanthroline-alcohol, and phenanthroline-imine ligands have been synthesized from I,10-phenanthroline via key Stille and Suzuki cross couplings. (C) 1999 Elsevier Science Ltd. All rights reserved.
Synthesis of acyclic dinucleating Schiff base-pyridine and schiff base-phosphine ligands
摘要:
5-tert-butyl-3-pyridyl-salicyaldehyde and 5-tert-butyl-3-diphenylphosphino-salicyaldehyde have been 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'-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'-pyridyl) salicyaldehyde reacted with optically active 1,2-diaminocyclohexanes to give chiral dinucleating Schiff base-pyridine ligands.
