The Comins' reagent is a triflyl-donating reagent that is used to synthesize vinyl triflates from the corresponding ketone enolates or dienolates.[1]

Sample Reaction With Comin's Reagent
Sample Reaction With Comin's Reagent

It was first reported in 1992 by Daniel Comins.[2] The vinyl triflates prepared are useful as substrates in the Suzuki reaction.[3]
