PROCESS FOR OBTAINING ARYL ESTERS BY O-DEALKYLATION AND APPLICATIONS |
| abstract |
Process for obtaining an aryl ester by O-dealkylation of an alkyl aryl ether in which an alkyl aryl ether is reacted with an acyl halide in the presence of a catalyst chosen from hexaalkylguanidinium salts and tetraalkylphosphonium salts. The alkyl aryl ether preferably has the formula Ar (OR) n in which R represents an alkyl group, in particular a methyl group, n is an integer from 1 to 6 and Ar represents a C6 to C1 4 aromatic radical, a coumarinyl group or a set of several phenyl radicals. This process can also make it possible to obtain an aromatic polyester. |
