| titleOfInvention | PROCESS FOR THE PREPARATION OF ALCOXY OR ARYLMETHOXY AROXYETHANES |
| abstract | The present invention is a novel process, with or without solvent, for manufacture of compounds of formula (a), wherein P is selected from phenyl and naphthyl; wherein R1 and R2 and R3 are each independently selected from hydrogen, alykl, alkoxy, aryl, aralkyl, aralkoxy, halogen, alkoxyalkoxy, and aralkoxyalkoxy; wherein R5 is selected from substituted or unsubstituted phenyl, and substituted or unsubstituted naphthyl, the substituents being each independently selected from alkyl (C1-C8), alkoxy (C1-C8), aroxy, aralkoxy (C1-C8) and halogen. The process comprises reacting substituted phenols or naphthols of the formula (b) with ethylene carbonate in the presence of a first catalyst selected from metal halide, quaternary ammonium halide and quarternary phosphonium halide thereby forming an intermediate of the formula (c), then reacting the intermediate with a first compound selected from alkyl or aralkylhalide, alkyl or aralkyl sulfate, and alkyl or aralkyl sulfonate together with a metal hydroxide in the presence of a second catalyst, the second catalyst selected from quaternary ammonium salt or quaternary phosphonium salt. |
