ABSTRACT:
Disclosed is a process for the preparation of organic esters and amides by reacting (a) a 5 to 60 mole % excess of an ester of (substituted-4-hydroxyphenyl) alkanoic acid with (b) (i) a C.sub.4 -C.sub.20 aliphatic alcohol or thioether alcohol having one or more hydroxyl groups or (ii) an amine of the formula, (R"').sub.2 N(CH.sub.2).sub.n R"" wherein R"' is hydrogen, C.sub.1-7 alkyl, C.sub.5-12 cycloalkyl, or C.sub.6-12 aryl, provided that one R"' is hydrogen, and R"" is hydrogen or N(R"').sub.2 wherein R"' is a defined above, in the presence of a catalyst system comprising a basic inorganic compound and a polar aprotic organic compound. The process provides higher yields of the desired product, shorter reaction times, and reduces the production of undesirable side-products.
