  2. Trifluoromethylation - Wikipedia

    en.wikipedia.org/wiki/Trifluoromethylation

    An early report (1949) describes the photochemical reaction of iodotrifluoromethane with ethylene to 3-iodo-1,1,1-trifluoropropane. [53] Reagents that have been reported for the direct trifluoromethylation of arenes are CF 3 I, CF 3 Br (thermal or photochemical), silver trifluoroacetate /TiO 2 (photochemical) and sodium ...

    4-Cyano-3-(trifluoromethyl)aniline, also known as 4-amino-2-(trifluoromethyl)benzonitrile, is a cyanated and trifluoromethylated derivative of aniline. It is the starting material in one of the chemical syntheses of the nonsteroidal antiandrogen bicalutamide .

    See Amino acid for the pK a values of all amino acid side chains inferred in such a way. There are also numerous experimental studies that have yielded such values, for example by use of NMR spectroscopy. The table below lists the model pK a values that are often used in a protein pK a calculation, and contains a third column based on protein ...

  5. Trifluoromethyl group - Wikipedia

    en.wikipedia.org/wiki/Trifluoromethyl_group

    Trifluoromethyl group covalently bonded to an R group. The trifluoromethyl group is a functional group that has the formula-CF 3. The naming of is group is derived from the methyl group (which has the formula -CH 3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H– CF 3, 1,1,1-trifluoroethane H ...

  6. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    A simple example is provided by the effect of replacing the hydrogen atoms in acetic acid by the more electronegative chlorine atom. The electron-withdrawing effect of the substituent makes ionisation easier, so successive pK a values decrease in the series 4.7, 2.8, 1.4, and 0.7 when 0, 1, 2, or 3 chlorine atoms are present.

  7. Trifluralin - Wikipedia

    en.wikipedia.org/wiki/Trifluralin

    It is unclear why trifluralin's exotic 4-trifluoromethyl was tested so early (1960), before more common candidates such as fluoro, bromo, or iodo. [ 7 ] By 1968, trifluralin was internationally available, including Australia and New Zealand, [ 6 ] and trifluralin was the 5th most used herbicide in the US, at 22,960,000 pounds (10,410 t) by 1974.
