QUATERNARY AMMONIUM SALTS USED AS PHASE TRANSFER CATALYST |
| 摘要 |
Novel quaternary ammonium salts of general formula (I) (I) 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. X? is a halogenide anion, such as Cl?, Br?, I?, are used as phase transfer catalysts, in heterogeneous ionic reactions wherein the reagents are in different pha se and have different polarity. |
