Formaldehyde → HCID 20072024, compound

Participants

Reaction Steps

0.572 g of cuprous oxide and 20 ml of hydrogen fluoride were placed in a Daiflon reaction vessel connected to a carbon monoxide buret, and reacted with carbon monoxide at 5° C. under 1 atm to form a copper carbonyl catalyst solution. 9.1 ml (100 mmol) of 1,3-butanediol and 3.0 g (100 mmol) of paraformaldehyde were slowly added to the catalyst solution at 5° C. and the mixture was stirred to conduct the reaction with carbon monoxide under 1 atm. 85 molar %, based on 1,3-butanediol, of carbon monoxide was reacted. The product was separated from the catalyst layer to obtain 9.1 g (yield: 70%) of 5-methyl-1,4-dioxepan-2-one.
