Dimethyl oxalate → HCID 12871863, compound

Participants

Reaction Steps

2 Equivalents of dimethyloxalate were added to a solution of 53 mg 18-crown-6 in 1 ml of diethylether at 25° C. A solid complex was formed immediately. The precipitated crystals were filtered off at atmospheric pressure and washed with 1 ml of a 0.425 M solution of dimethyloxalate in diethylether. The crystals contained 80% of the starting amount of 18-crown-6. A melting point range of 62°-82° C. was observed.
