Synthesis of tripyridiniumylpropenyl anions from tripyridiniumylcyclopropanes and -cyclopropenes
摘要:
The syntheses of three stable, isolatable tripyridiniumylpropenyl anions are described. 1,2,3-Tris(4-(N-methylpyridiniumyl))propenyl anion and 1-(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))propenyl anion were prepared by treating the corresponding cyclopropane with a base. 1,3-Bis(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))propenyl anion was prepared by nucleophilic attack of benzenesulfinate anion on 3-(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))cyclopropene. Reduction of this cyclopropene gave either 1-(benzenesulfonyl)-1,2,3-tris(4-(N-methyl)pyridiniumyl))propenyl anion or hexakis(4-(N-methylpyridiniumyl))benzene depending on the solvent used.

The invention disclose a hydrogen fluoride containing composition comprising hydrogen fluoride and a compound which is liquid in the standard state (25 °C, 1 atmosphere) and has a boiling point of 120 °C or more and pka of 12 or more at 25 °C, and use of the composition for a fluorination agent.
The compound which can be preferably used is represented by the formula (1):
wherein R1 to R4 are a substituted or unsubstituted alkyl or aryl group and can be the same or different, and R1 or R2 or R3 and R4 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom, or R1 and R3 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom.
The fluorination agent of the invention exerts effect with a similar reaction mechanism to hydrogen fluoride, can be applied to the halogen exchange reaction of a halogen containing organic compound, and can produce a fluorine containing compound with safety and ease without specific equipment or technique.
