Synthesis of per(poly)fluoroalkyl substituted alkenes and alkynes—Utilizing potassium fluoride supported on alumina as a dehydrohalogenating agent

Potassium fluoride on alumina was proved to be an efficient dehydrohalogenating agent for the synthesis of per(poly)fluoroalkyl substituted alkenes and alkynes. The reaction was simple, mild and the yields ranged from good to excellent.
