The first 1,5- and 2,5-disubstituted fluorous tetrazoles are sought as potential surfactants. Direct alkylation of monosubstituted tetrazoles using alkyl iodides and triflates is compared with the Mitsunobu reaction. Mitsunobu conditions provide advantage for perfluoroalkylethylation, in terms of selectivity towards the 2,5-isomers and overall yield, but are not applicable to perfluoroalkylmethylation
