Diphenyl carbonate → HCID 86747471, compound

Participants

Reaction Steps

A solution of diphenyl carbonate (5.35g/0.025 mole) and acetophenone oxime (13.5g/0.1 mole) in 25 ml toluene was placed in a 250 ml 3-neck flask fitted with a thermometer and reflux condenser. The mixture was heated to about 116° C. for one (1) hour under nitrogen. Toluene and all low-boiling components were removed under vacuum (70°-75° C. at 2 mm Hg). The syrup gave a solid upon standing. The solid was filtered and washed with 15 ml petroleum ether. The crude product was then dissolved in 20 ml ether and hexane was added to turbidity. After filtering and drying 7.2 g of colorless crystals appeared (m.p. 110°-112° C.). Yield: 97.3%. Confirmation of the compound as acetophenone oxime carbonate was obtained through IR and NMR spectral analyses.
