Perfluorinated sulfonic acid resin (Nafion-H) catalysed trans-t -butylation of 7- t -butyl-1,3-disubstituted pyrenes;a new route for the preparation of 1,3-disubstituted pyrenes
The perfluorinated sulfonic acid resin (Nafion-H) catalyst is found to be effective in promoting the trans-t-butylation of 7-t-butyl-1,3-dialkylpyrenes to afford the corresponding 1,3-dialkylpyrenes in good yields.
