M. Bourgault et al., SYNTHESIS AND CHARACTERIZATION OF 4-ALKENYL AND 4,4'-DIALKENYL-2,2'-BIPYRIDYL LIGANDS BEARING PI-DONOR SUBSTITUENTS, Canadian journal of chemistry, 75(3), 1997, pp. 318-325
The synthesis of a new series of pi-donor mono- and disubstituted viny
l bipyridines (donor = 4-R2N-C6H4-; 4-RO-C6H4; (C5H5)Fe(C5H4-); (C5H5)
Ru(C5H4-)) has been achieved by reaction of the mono- and dilithio spe
cies of 4,3'-dimethyl-2,2'-bipyridine and the monolithio species of 4-
nonyl-4'-methyl-2,2'-bipyridine with the appropriate aldehydes. Their
H-1 NMR and UV-visible characterizations are reported.
