ACYLATION OF AROMATICS UNDER MICROWAVES I N THE PRESENCE OF GRAPHITE

Under microwave irradiation, acylations of aromatic compounds could be achieved in the presence of graphite powder, used either to support t he reagents (dry medium), or in small amount (solid-liquid medium). Th e process takes advantage both of the interaction of the graphite with the electromagnetic field and with the organic compounds. Acylations were achieved in an open reactor and at temperatures notably higher th an the boiling point oft he reagents. A catalytic effect of metallic i nclusions present on the graphite surface, in particular iron ones (ma gnetite), has been established. (C) Academie des Sciences/Elsevier, Pa ris.
