Aloisi, Giangaetano published the artcileCharge transfer complexes between halogens and pyridines. 4. Effect of the acid strength of the acceptors, Quality Control of 6443-90-9, the publication is Transactions of the Faraday Society (1970), 66(12), 3075-80, database is CAplus.
Charge-transfer equilibrium between Br, I, ICl, and IBr as acceptors and various meta- and para-substituted pyridines as donors were studied spectrophotometrically in CCl4 at 30°. Formation constant of the complexes were correlated with Hammett’s substituent constant, ionization constant of the donors, and acid strength of the acceptors. Correlations with intermol. and(or) interhalogen spectral parameters are also discussed.
