The synthesis of fluorotelomer alcohols requires a varying number of tetrafluoroethylene monomers that form an oligomer with a pentafluoroethyl iodide telogen. The fluorinated iodide then undergoes an addition with ethylene to form an organoiodine compound with increased synthesis possibilities. [ 1 ]

An idealized synthesis of 1-octanol is shown: Al(C 2 H 5) 3 + 9 C 2 H 4 → Al(C 8 H 17) 3 Al(C 8 H 17) 3 + 3O + 3 H 2 O → 3 HOC 8 H 17 + Al(OH) 3. The process generates a range of alcohols that are separated by distillation. Many higher alcohols are produced by hydroformylation of alkenes followed by hydrogenation.
The diagram below summarizes the potential changes that it can undergo. Along with what is seen above, other reactive forms of FAD can be formed and consumed. These reactions involve the transfer of electrons and the making/breaking of chemical bonds .
The metabolic pathway continues through a series of enzymatic modifications to yield flavanones → dihydroflavonols → anthocyanins. Along this pathway, many products can be formed, including the flavonols , flavan-3-ols , proanthocyanidins (tannins) and a host of other various polyphenolics.
2-Fluoroethanol was originally synthesized by treating 2-chloroethanol with potassium fluoride, in a simple Finkelstein reaction. [5] The product has a lower boiling point that the starting material and may be conveniently isolated by distillation.
The labeled [18 F]FDG compound has a relatively short shelf life which is dominated by the physical decay of fluorine-18 with a half-life of 109.8 minutes, or slightly less than two hours. Still, this half life is sufficiently long to allow shipping the compound to remote PET scanning facilities, in contrast to other medical radioisotopes like ...
