This report describes a simple two-phase process for the oxidation of benzo[b]thiophene, the generation of aromatic nitriloxides, the cycloaddition of the latter with the oxidized benzo[b]thiophene and the halogenation of the cycloadducts. All these reactions can be effected in a one-pot procedure.

1,3-Dipolar addition of arylnitriloxides with some olefinic dipolarophils on aluminum in dry media and under microwave

Isoxazolines are prepared in good yields on solid mineral support in 'dry media' and under microwave irradiation in domestic ovens.
