The Synthesis of Benzhydrol Derivatives via Phenylation of Aromatic Aldehydes in the Presence of DPPE-Copper Nanometal Complex

Cu/Fe3O4 magnetic nanometal was synthesized and characterized by FT-IR spectroscopy, Energy Diffraction X-ray (EDX) spectroscopy, Electron Scanning Microscope (SEM), and Vibrating Sample Magnetometer (VSM). In continue, the complex of synthesized magnetic nanometal with the dppe(1, 2-diphenylphosphine ethane) ligand was used in 1, 2-nucleophilic addition of aryl group to aromatic aldehydes using phenylboronic acid. Alcoholic products were obtained with a good yield (up to 95%) in an acceptable time (up to 24 hours). The catalyst was magnetically recovered and reused in the addition reaction five times without a significant reduction in catalytic activity and yield. The structure of products was determined using melting point and 1H NMR, 13C NMR, and FT-IR spectroscopies
