TBAF-Promoted Elimination of Vicinal Dibromides Having an Adjacent O-Functional Group: Syntheses of 2-Bromoalk-1-enes and Alkynes

[摘要]：Syntheses of 2-bromoalk-1-enes and alkynes were achieved in good yields by dehydrobromination of vicinal dibromides with tetrabutylammonium fluoride. Neighboring O-functional-group participation is important in determining elimination reactivity.
