Synthesis of phenyl and ester substituted vinyl fluorides via reduction and olefination of esters

A reduction-olefination sequence has been used to convert ethyl pentafluoropropanoate 6 to 1-fluoro-1-phenyl-2-pentafluoroethyl ethene 7 and ethyl 2,4,4,5,5,5-hexafluoro-2-pentenoate 8. Addition of lithium diethyl α-fluorobenzylphosphonate [(EtO)2P(O)CFPh]- Li+ 4 or lithium fluorocarboethoxymethylene dialkylphosphonate [(RO)2P(O)CFCO2Et]- Li+ 5 (R = Et, i-Pr) to a THF solution of fluorinated aldehydes prepared in situ from 6 and diisobutylaluminum hydride (DIBAL) affords the vinyl fluorides C2F5CH=CFPh 7 and C2F5CH=CFCO2Et 8 in good yields. However, yields of the final products 7 and 8 are low when in situ reduction of 6 to aldehyde was performed in the presence of lithium salts of 4 or 5.
