The Wittig reaction of perfluoro acid derivatives: access to fluorinated enol ethers, enamines, and ketones

The Wittig reaction of perfluoro acid derivatives: access to fluorinated enol ethers, enamines, and ketones. Begue, Jean Pierre; Bonnet-Delpon, Daniele; Mesureur, Dany; Nee, Gerard; Wu, Sheng Wen (CNRS, Thiais 94320, Fr.). J. Org. Chem., 57(14), 3807-14 (English) 1992. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 21 (General Organic Chemistry) The prepn. of novel perfluoroalkyl-substituted compds. in good yields is described. This prepn. involves the Wittig reaction of a phosphonium ylide with perfluoroalkyl acid derivs. The influence of the structure of the starting alkylidenetriphenylphosphoranes, the perfluoroalkyl reagents, and the reaction conditions has been investigated. Trifluoroacetamides lead to a Z/E mixt. of enamines. 354-76-7 is also in the experiment.Several reagents such as 354-76-7 is used here. Perfluoroalkyl esters, e.g., CF3CO2Et, lead to only the (Z)-enol ethers, e.g., CF3C(OEt):CHCH2CH2Ph, when reactions are performed with NaNH2 as a base and to 1-perfluoroalkyl ketones, e.g., CF3CO(CH2)3Ph, when reactions are performed with BuLi. ..
