Heck Reactions Starting from Silyl Enol Ethers - A Simple One-Pot Nonaflation-Coupling Procedure for the Synthesis of 1,3-Dienes

Article abstract of DOI:10.1055/s-1997-976

Starting from silyl enol ether 4 the corresponding alkenylnonaflate 5 was generated by treatment with nonafluorobutanesulfonyl fluoride (NfF) and a catalytic amount of tetra-n-butylammonium fluoride (TBAF). By Pd-catalysis 5 was directly Heck-coupled with
