Acetyl bromide → HCID 54184049, compound

Participants

Reaction Steps

16.9 g (0.189 mol) of acetyl bromide are added dropwise to 26.0 g (0.126 mol) of 3-methoxy-3-phenyl-2,4-dioxa-bicyclo[3,2,0]heptane (stereoisomer mixture), at 20° to 30° C. After the reaction has subsided, the mixture is heated to the reflux for 4 hours. Distillation in vacuo gives 32.5 g (99%) of trans-1-bromo-2-benzoyloxy-cyclobutane as a colourless oil of boiling point0.2 94°-97°, which solidifies in the receiver.
