A de novo synthesis of Cr-embedded MOF-199 was developed for the first time. This Cr-MOF-199 material was further derived into CuO/CuCr2O4 composites with a porous and uniform structure. The obtained bimetallic oxides with a porous structure were further applied in phenol hydroxylation. [ABSTRACT FROM AUTHOR]

The acid-catalyzed reactions of photochemically generated tetrahydrocarbazole peroxides with anilines have been studied experimentally and computationally to identify the underlying reaction mechanism. The kinetic data indicate a reaction order of one in the hydroperoxide and zero in the aniline. Computational investigations using density functional theory support the experimental findings and predict an initial tautomerization between an imine and enamine substructure of the primarily generated tetrahydrocarbazole peroxide to be the rate controlling step. The enamine tautomer then loses hydrogen peroxide upon protonation, generating a stabilized allylic carbocation that is reversibly trapped by solvent or aniline to form the isolated products., (© 2015 WILEY-VCH Verlag GmbH & Co.
