Versuchsvorschrift

To a solution of acryloyl isocyanate (9.7 g; 100 mmol) in dichloroethane (20 g), a solution of t-butanol (7.4 g; 100 mmol) in dichloroethane (20 g) was dropwise added under ice-cooling in 5 minutes. The solvent was removed by evaporation under reduced pressure to-give t-butyl N-acryloylcarbamate as crude crystals, which were recrystallized from chloroform to give colorless needles. M.P., 131°-132° C.
