    • If more recent data were available, the percentage of fluorinated pharmaceuticals and agrochemicals would be substantially different. Thus, according to conversations of the corresponding author with leading scientists form pharmaceutical industry at the recent (2005) GRC "Organic Reaction and Processes", the number of fluorinated drug-candidates which are currently under development is at least 80%.

    • As suggested by the editor, the alternative mechanism may be "represented as a series of two electrocyclic reactions of the intermediate carbanion obtained from intermediate 14, the first an 8-electron ring opening to an oxyanion triene, which then could undergo an oxyanion accelerated 6-electron electrocyclic ring closure to give the suggested intermediate 15".
