A new C2 diazabiaryl ligand cyclo-octadipyridine (1) has been prepared, and an X-ray crystallographic analysis of the tetracarbonyl molybdenum complex of (1) showed that the torsional angle between the alkenic bonds is 51 deg; attempted resolution of (1) with a chiral palladium complex apparently afforded a single diastereoisomer, whose stereochemical configuration was substantiated by one-dimensional and two-dimensional proton NMR studies.
The chemistry of novel C2 diazabiaryl ligands: Cycloocta[2,1-b:3,4 -b′]dipyridine, cycloocta[2,1 -b:3,4-b′]diquinoline and their related compounds

Three novel cyclooctadiazabiaryl ligands, namely cycloocta[2,1-b:3,4-b′]dipyridine (3), cycloocta[2,1 -b:3,4-b′]diquinoline (4) and cycloocta[2,1-b:3,4-b′]di[1,8]naphthyridine (5) have been synthesized and a number of metal complexes have been prepared for these novel ligands. The energy barrier to ring inversion of these compounds have also been studied.
