摘要：

A new heterogeneous palladium complex of 2-aminothiophenol supported on nanomagnetic gamma-Fe2O3 was synthesized and characterized using various methods. The catalyst was used as a magnetically recoverable heterogeneous palladium catalyst for phosphonation reactions via C-P bond formation. Using this method, a wide range of electrophilic benzenes was coupled successfully with phosphite esters (triethyl/tri-isopropyl/triphenylphosphite and diethyl/di-isopropyl/diphenylphosphite) in aqueous micellar solution to generate the corresponding arylphosphonates in good to high yields. The catalyst was separated using an external magnet and reused for six consecutive cycles without any significant loss of its reactivity. Copyright (C) 2015 John Wiley & Sons, Ltd.
