In the presence of Pd- and Cr-containing catalysts applied to γ-Al2O3 or sibunite 4,5,6,7-tetra-hydroindole is converted into indole. Indole was obtained in quantitative yield on sulfided 0.15-0.5% Pd/γ-Al2O3 catalyst at 360°C and on catalysts containing 5% Cr2O3, 5% La2O3 (or 5% polirit), 1% K2O/89% γ-Al2O3 at 475-480°C.
