The N ‐bromosuccinimide bromination of α‐benzylidene‐γ‐butyrolactone ( 1 ) proceeds with allylic rearrangement to yield 3‐(α‐bromobenzyl)‐2(5 H )‐furanone ( 3a ). A number of reactions of this compound are described. Bromination of 1 with elemental bromine leads to α‐bromo‐α‐(α‐bromobenzyl)‐γ‐butyrolactone.
