Methyl Isocyanate → HCID 86733045, compound

Participants

Reaction Steps

A mixture of 1-trifluoromethylthio-2-propanone oxime (0.02 mole) from Step 2, methyl isocyanate (0.22 mole) and 2 drops of triethylamine in 25 ml of dichloromethane was heated at its reflux temperature overnight. The solvent was removed by evaporation under vacuum. The residual oil was recrystallized from a mixture of petroleum ether and diethyl ether to give a pure sample of 1-trifluoromethylthio-2-propanone O-methylcarbamoyl oxime, m.p. 56°-58°C. The structure of the product was confirmed by elemental and spectral analyses.
