Solid Superacid Catalyzed Efficient Synthesis of 2-Diethylaminoethyl Aryloxyacetates

摘要

2-Diethylaminoethyl aryloxyacetates are prepared efficiently in 75～95% yields by condensation of the corresponding aryloxyacetic acids with 2-diethylaminoethanol in the presence of catalytic amount of solid superacid SO4 -/Fe2O3.
