C 31 Catalyst-free transformations of diethyl 2-ethoxymethylenemalonate and diethyl polyfluorobenzoylmalonates in water / D. N. Bazhin, Yu. S. Kudyakova, Ya. V. Burgart, V. I. Saloutin // Tetrahedron Letters. - 2012. - Vol. 53, №15. - С. 1961-1963 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 1,3,5-BENZENETRICARBOXYLATE -- WATER -- POLYFLUOROBENZOYLMALONATES Аннотация: The unusual transformation of diethyl 2-ethoxymethylenemalonate into triethyl 1,3,5-benzenetricarboxylate is described. This one-pot reaction proceeds in water without any catalyst in a good yield. One of the proposed intermediates of this process is also used under similar conditions to give the desired trisubstituted benzene. A catalyst-free, efficient, practical, and convenient process in water based on deethoxycarbonylation has been developed to form ethyl polyfluorobenzoylacetates in a high yield from diethyl polyfluorobenzoylmalonates \\\\Expert2\\nbo\\Tetrahedron Letters\\2012, v. 53, p. 1961.pdf |
