Novel quaternary ammonium salts of general formula (I) ##STR1## wherein: R is a saturated or unsaturated, linear or branched alkyl radical of C.sub.1 to C.sub.8. R' is a saturated or unsaturated, linear or branched alkyl radical of C.sub.1 to C.sub.12, or a benzyl radical. n is a number equal to 2 or 3. X.sup..theta. is a halogenide anion, such as Cl.sup..theta., Br.sup..theta., I.sup..theta., are used as phase transfer catalysts, in heterogeneous ionic reactions wherein the reagents are in different phase and have different polarity.
