The reaction of primary alcohols with trifluoromethanesulfonic anhydride in the presence of poly(4-vinylpyridine) [or poly(2,6-di-tert-butyl-4-vinylpyridine)] allows the isolation of the corresponding alkyltriflates in good yields. The quaternisation of 3,8-bis(ethoxycarbonylamino)-6-phenylphenanthridine (1) using these alkyltriflates was found to proceed smoothly at room temperature in nitrobenzene
