Alkylating reagents such as boron trifluoride-methanol, sulfuric acid-methanol, methanol-hydrochloric acid and methyl iodine-sodium hydride do not react efficiently with pyrithiobac. Trimethylsilyldiazomethane may be used for the methyl-ation of pyrithiobac. 

The Liotta procedure involved slurrying coal in an aqueous solution of tetrabutylammonium hydroxide to remove acidic protons, followed by addition of methyl iodide as alkylating agent. This mixture was then stirred vigorously for 12-72 hrs. depending upon the extent of alkylation desired. After all lation, the moist coal sample was roto-evaporated to remove excess THF and methyl iodine, followed by exdiaustive extraction with water to remove tetrabutylammonium iodide produced during all lation. Finally, the treated coal was vacuum dried (50 C, 0.1 torr, 24 hours) before use.

The process of methylation with C-11 methyl iodine eventually became widely used for labeling many drugs. To produce C-11, because of its 20-minute half-life, it is necessary to have a cyclotron close to where the chemical syntheses and imaging procedures are carried out. 

Arylsulfonyl)methyl]iodine(III) bis(trifluoroacetates) 41 can be prepared from the respective iodomethyl sulfones 40 using a similar oxidation procedure (Scheme 2.20) [138]. Bis(trifluoroacetates) 41 can be isolated at 0 °C, but are unstable at room temperature and can spontaneously decompose with explosion.

III-23. The usual, conservative, approach is to neglect the solubility of noble gases in the pool water. However, a significant fraction of the iodine and caesium will be retained in the pool water. The release of iodine into the atmosphere above the pool may best be described in terms of a partition coefficient (the ratio of the volumetric activity concentrations (Bq/m ) in air and in water). For that part of the iodine present in organic compounds such as methyl iodine no solubility in water is conservatively assumed in many States.
