Abstract

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.

Key words

tetrabutylammonium fluoride - elimination - 2-bromoalk-1-enes - alkynes - vicinal dibromides
