Dimethyldioxirane (DMDO), a widely used oxidant in organic synthesis is considered an environmentally friendly oxygen transfer reagent because acetone is the only byproduct formed in its oxidation reactions. This work describes the isolation of the main constituents (terpenes) in the essential oils obtained from Tagetes lucida, Cymbopogon citratus, Lippia alba and Eucalyptus citriodora, their epoxidation with DMDO in acetone solution and the characterization of the resulting epoxides by GC-MS (EI) and NMR. This is one of the first reports involving the application of dioxirane chemistry to essential oils in order to generate modified compounds with potential uses in several areas of medicine and industry.

Synthesis of some new dioxomolybdenum(VI) complexes having general formula [MoO2(mac)](acac)2, (where mac = tetraazamacrocyclic ligands derived from condensation of furil with 1,2-diaminobenzene or 2,3-diaminopyridine and their reaction with ?-diketones) using dioxometal ion as kinetic template are reported. The prepared complexes have been characterized by molar conductance, elemental analyses, infrared and electronic data. The spectral data indicate that ligands act as tetradentate chelating agent. Due to their biological relevance, molybdenum catalyzed oxygen transfer reactions have great interest. All the dioxomolybdenum(VI) complexes have octahedral geometry with six coordination.
