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.
