実験手順

Bis(trimethylsilyl)chloromethane (Aldrich) (14.68 g, 0.075 mole), sodium methacrylate (8.96 g, 0.0825 mole), Adogen 464 (Aldrich) (1.70 g), and phenothiazine (0.05 grams) were placed in a round bottom flask equipped with a condenser, mechanical stirrer and a nitrogen inlet. The flask was charged with 200 ml acetonitrile and heated to reflux while stirring. After 4 days, the mixture was filtered to remove the solids and the solvent was removed in a rotary evaporator. Fractional distillation under reduced pressure gave 10.90 grams (60% yield) of a clear liquid at 46-48° C. at 0.5 mm pressure.
