Fluoropyridinium salts, in most cases, are freely soluble in polar solvents such as acetonitrile, but insoluble or sparingly soluble in nonpolar organic solvents.38 39 The solubilities of 1-fluoro-pyridinium triflate, tetrafluoroborate, hexafluoroantimonate and perchlorate in dichloro-methane are 0.63, 0.05, 0.09 and 0.035 mg cm 3, respectively, and of 1-fluoropyridinium triflate in tetrahydrofuran is 1.71 mg cm-3. The salts were dissolved in water and decomposed very slowly at room temperature. When a solution of 1-fluoropyridinium triflate in water was allowed to stand for 14 days at room temperature it decomposed completely to give pyridin-2-ol in 66% yield. 1-Fluoropyridinium salts with non-nucleophilic counteranions are generally stable crystals with high melting points. [Pg.439]

Nitronium tetraHuoroborate and m dinitrobenzene were added to fluoro-sulphuric acid and cooled in a dry ice/acetone bath. The temperature was gradually raised to ISO C. After three hours of heating the reaction mixture was poured on to crushed ice. The nitro product was extracted with dichloro-methane, washed with sodium hydrogen carbonate solution and dried over magnesium sulphate. The yield of sym-trinitrobenzene was 61.6% with 5% unreacted m-dinitrobenzene. [Pg.433]

Oxidation of ketone acetals and ethers.5 Ketones can be regenerated from the ethylene acetal derivatives by treatment with trityl Huoroborate in dry dichloro-methane (N2) at room temperature. Thus the reaction of trityl Huoroborate with cyclohexanone ethylene acetal results in cyclohexanone (80%) and triphenylmethane. The reaction thus involves hydride transfer to the triphenyl carbonium ions. Triethyl-oxonium Huoroborate can also be used but is somewhat less effective than trityl fluoro-borate. [Pg.287]
