The Photoinitiation of Substitution Reaction of Halogen in Bromonaphthol and Iodophenol by Aromatic Amines

Abstract

At photolysis of 1-bromo-2-naphthol and o-iodophenol an increase of the quantum yield of substitution reaction of halogen by sulphogroup in aqueous solution of sodium sulfite and by hydrogen in organic solvents in the presence of amines (diphenylamine, carbazole) is observed. At flash photolysis the triplet quenching of 1-bromo-2-naphthol by diphenylamine with a constant rate 7.107 M-1s-1 is observed. The mechanism of photoinitiation substitution reaction is due to electron transfer.
