Abstract An efficient and green procedure has been developed for the synthesis of
monoarylidenes of cyclic and heterocyclic ketones. The reaction was carried out under
solvent-free conditions in the presence of a catalytic amount of nanosized magnetite
(Fe3O4). The catalyst was easily removed by using an external magnet. The structures
of the products were deduced from their 1H NMR, 13C NMR, and infrared spectroscopy
and mass spectrometry.
