Abstract: It has been found that the condensation of 3,6-dithia-3,4,5,6-tetrahydrophthalic
anhydride or phthalic anhydride with mono-, di-, and trimethyl
derivatives of nitrogen-containing heterocycles gives the corresponding
2-substituted indandiones or their dithia analogs. The structure of the
formed compounds has been determined on the basis of their n.m.r. and i.r.
spectra. It has been found that only monoderivatives of the respective
indandiones are formed.
