In two reports Hanzawa and co-workers described a mild and facile Pictet-Spengler reaction catalyzed by perfluorooctane sulfonic acid (PFOSA) in water <07T4039 07TL835>. Many of their examples outline the reaction of 3,4-dimethoxyphenethylamines 124 with a variety of aldehydes catalyzed by PFOSA in water using l,l,l,3,3,3-hexafluoro-2-propanol (HFIP) as an additive resulted in the formation of 1,2-disubstituted tetrahydroisoquinoline derivatives 125 in high yield.

In the past years, elucidation of transformation products of per- and polyfluorinated compounds (PFC) has been a task frequently approached by analytical chemists. It has been estimated that biotransformation contributes to approximately 0.1-5% with respect to perfluorocarboxylic acid (PFCA) historical global emissions [1]. For perfluorooctanesulfonyl fluoride (POSF)-based compounds such as perfluorooctane sulfonic acid (PFOS), biotransformation products probably affect environmental burden marginally, although no distinct estimations have been made so far [2].

Perfluorinated organic compounds constitute a unique class of POP. They occur as completely fluorinated hydrocarbon derivatives, such as CF4, in the atmosphere, where they are regarded as atmospheric pollutants and potential greenhouse gases (see Chapter 7). Other perfluorinated compounds that are organic acids or their salts have been encountered as water pollutants. Most commonly cited are salts of perfluorooctane sulfonic acid others include salts of perfluorinated carboxylic acids, such as perfluorohexanoic acid ...
