Synthesis and chemistry of α-iodoperfluoroacid esters
摘要:
The title compounds have been synthesized by irradiation of acetonitrile solutions of perfluoroacid esters and diesters containing tetrabutylammonium iodide. They are versatile synthetic intermediates from which ketenes, Reformatsky adducts, alpha,beta-unsaturated esters and alpha-hydroesters can be prepared. (c) 2006 Elsevier B.V. All rights reserved.
1-Phosphonyloxy--1-alkenephosphonates, easily prepared from -alkanoic acid chlorides and triethyl phosphite, undergo a unique fluoride ion-catalyzed reaction with primary and secondaryamines or alcohols to afford the corresponding α, β-unsaturated -carboxylic acid derivatives in excellent yields, along with diethyl fluorophosphate and phosphite.
