M. Albrecht et al., THE WITTIG APPROACH TO ETHYLENE-BRIDGED CATECHOL AMINOPHENOL DERIVATIVES - POTENTIAL LIGANDS FOR METALLOSUPRAMOLECULAR CHEMISTRY/, Journal fur praktische Chemie, Chemiker-Zeitung, 340(6), 1998, pp. 562-566
The sequential ethylene-bridged catechol/aminophenol derivatives 2-H-3
and 3-H-3 are potential ligands for metal-directed self-assembly proc
esses. They are prepared via Wittig-reaction followed by a high yield
reduction step with up to three simultaneous transformations.
