実験手順

Positively charged bi-functional precursor molecules for self-assembly. Potassium cyanide (50 mg) was added to a solution of methyl isonicotinate (1.17 g, 0.01 mole) and 50% hydroxylamine in water (1.3 g, 0.02 mole) in 10 mL tetrahydrofuran and 5 mL methanol. After stirring the mixture at room temperature for 18 hours, the precipitate was filtered and washed with diethyl ether and dried to give analytically pure N-hydroxy isonicotinamide. The latter was added to 5% methyl iodide in methanol and stirred at room temperature for two days. Methanol was evaporated under reduced pressure and the solid residue was crystallized from ethanol resulting in pure 4-hydroxamido-N-methylpyridinium iodide.
