Quaternary ammonium salts used as phase transfer catalyst
-
, (2008/06/13)
Novel quaternary ammonium salts of general formula (I) STR1 wherein: R is a saturated or unsaturated, linear or branched alkyl radical of C1 to C8. R' is a saturated or unsaturated, linear or branched alkyl radical of C1 to C12, or a benzyl radical. n is a number equal to 2 or 3. Xθ is a halogenide anion, such as Clθ, Brθ, Iθ, are used as phase transfer catalysts, in heterogeneous ionic reactions wherein the reagents are in different phase and have different polarity.

, p. 565 - 580 (2007/10/02)
Alkyl phenyl 2,3-epoxycarboxylates from the well-known Darzens glycidic esters synthesis react under very mild conditions with pyridinium-poly-hydrogen fluoride to give corresponding 3-fluoro 3-phenyllactates in almost quantitative yields with a high regio and stereoselectivity.This method can be applied succesfully to other flycidic derivatives: glycidoamides, glycidonitriles, glycidoiminoesters...The spectrometric properties (IR, NMR) are presented.
