Sodium Hydroxide → HCID 178440550, compound

Participants

Reaction Steps

34.75 g of hydroxylamine hydrochloride are dissolved in water, and 109 g of methallylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride are added. There are then added dropwise, with stirring, 40 g of 50% aqueous sodium hydroxide solution, and the mixture is refluxed for 1 hour. All volatile components are afterwards distilled off, the residue is taken up in toluene, the precipitated sodium chloride is filtered off, and the toluene is removed in a rotary evaporator (150° C., 2000 Pa). There are thus obtained 98.5 g of a highly viscous liquid (90% of theory), which is not distillable up to 200° C./2.5 Pa, since the product presumably is in the form of a dimer.
