Ishikawa’s Reagent

Chemfiles Volume 5 Article 1

Ishikawa’s reagent (N,N-diethyl-1,1,2,3,3,3-hexafluoropropylamine) has also demonstrated utility in fluorination. In a recent example, Ishikawa’s reagent has been used in a clean and reproducible fluorination protocol on an intermediate in the total synthesis of 26-fluoroepothilone B(Scheme 14)1
