A novel experimental procedure to obtain carbonyl compounds under microwave irradiation from activated olefins and supported iodobenzene diacetate is described. By varying the reaction conditions it is possible to generate the corresponding aldehydes in reasonable-to-excellent yields and selectivities. The methodology is simple, clean, and reproducible and presents short reaction times. Using isosafrol, isoeugenol, and anethol it was possible to produce piperonal, vanillin and p-anisaldehyde, respectively.
Method for the isomerization of oxiranes

, (2008/06/13)
The method for the isomerization of oxiranes of the general formula: STR1 wherein R1 and R3 are hydrogen; R2 is alkyl or alkylene groups of 3 to 26 carbon atoms or the phenyl group which may also be substituted, and R4 is hydrogen or alkyl from 1 to 26 carbon atoms and in which the carbon atoms of the epoxy ring can also form components of a cyclic system, wherein as a catalyst there is used alkali iodide and a polyethyleneglycol with an average mol mass of 400 to 10,000 with a boiling point, preferably above the boiling point of the carbonyl compounds that are formed.
