Zusammenfassung
Owing to its relatively high basicity (pKa1 = 3.37), 3,3'-bipyridazine (L) yields M(CO)4L (M = Cr, Mo, W) which have both metal-to-ligand charge transfer absorption max. at longer wavelengths than corresponding 2,2'-bipyrimidine and 2,2'-bipyrazine compds. After 4,4'-bipyramidine, 3,3'-bipyridazine is the 2nd-best p acceptor among the sym. bidiazines with a-diamine structure. Redox potentials were detd. on SciFinder(R)
