Synthesis of a Novel Optically Active C 2 ‐Symmetric 2,2′‐Bipyridine
Optically active 2,2′‐bipyridine ( S,S )‐ 1 was synthesized by radical cyclization and a nickel(0)‐mediated coupling of enantiomerically pure bromopyridine ( S )‐ 8 . Palladium, copper, and cobalt complexes of 1 were prepared. The solid‐state structures of meso ‐ 1 and 11 were determined by X‐ray cr...

| Zusammenfassung: | Optically active 2,2′‐bipyridine (
S,S
)‐
1
was synthesized by radical cyclization and a nickel(0)‐mediated coupling of enantiomerically pure bromopyridine (
S
)‐
8
. Palladium, copper, and cobalt complexes of
1
were prepared. The solid‐state structures of
meso
‐
1
and
11
were determined by X‐ray crystal structure analysis. |
