Methyl chloroformate → HCID 178497430, compound

Participants

Reaction Steps

To a tetrahydrofuran solution of methoxycarbonyl cyclopentadienyl sodium (28 mmol/28 ml) preparated by the Rausch method, a tetrahydrofuran solution of methyl chloroformate (2 g/30 ml) was added under cooling with ice. When the solution reached room temperature, it was filtered and concentrated under reduced pressure. Then, methylene chloride was added thereto to precipitate slightly pink precipitates. The precipitates were collected by filtration and dried to obtain 1.23 g of dimethoxycarbonylcyclopentadienyl sodium.
