Synthesis and characterization of 4-alkenyl and 4,4′-dialkenyl-2,2′-bipyridyl ligands bearing π-donor substituents

Article abstract of DOI:10.1139/v97-036

The synthesis of a new series of π-donor mono- and disubstituted vinyl bipyridines (donor = 4-R₂N-C₆H₄-; 4-RO-C₆H₄-; (C₅H₅)Fe(C₅H₄-); (C₅H₅)Ru(C₅H₄-)) has been achieved by reaction of the mono- and dilithio species of 4,4′-dimethyl-2,2′-bipyridine and the monolithio species of 4-nonyl-4′-methyl-2,2′-bipyridine with the appropriate aldehydes. Their ¹H NMR and UV-visible characterizations are reported.
