Sequential synthesis of rigid multi-bipyridine ligands bearing diethynyl/phenyl solubilizing fragments
Khatyr, Abderrahim,Ziessel, Raymond
, p. 3837 - 3841 (2007/10/03)
Reliable and practical synthetic routes for the construction of multitopic bipyridine ligands are presented. The first series contains the chelating fragments connected via an ethynyl function and the second series is built from an alternation of ethynyl/phenyl/bipyridine modules. The synthetic protocol is based on sequential Pd-promoted cross-coupling reactions between selected bis-bpy or ethynyl/phenyl/bpy intermediates of increasing size. The ligands bearing functionalized 1,4-diethynyl-2,5- di(dodecyloxy)benzene subunits are soluble in chlorinated solvents. (C) 2000 Elsevier Science Ltd.
Synthesis of quasi-linear and segmented bis- to penta-2,2'-bipyridine polytopic ligands built via a convergent approach
Khatyr,Ziessel
, p. 7814 - 7824 (2007/10/03)
Reliable and practical routes for the preparation of segmented oligomeric 2,2'-bipyridine-based ligands possessing rigid and conjugated spacers are presented. The first series of ligands bears a single alkyne function as a bridge and has been built by Pd(
