A novel, environmentally friendly procedure has been developed for the preparation of secondary or tertiary amines by one-pot reductive amination of carbonyl compounds using sodium borohydride in the presence of a magnetically recoverable sulfonic acid supported on hydroxyapatite-encapsulated-γ- Fe2O3 [γ-Fe2O3@HAP-SO 3H] at room temperature. The catalyst was easily separated from the reaction mixture by applying an external magnet and reused for six cycles without significant loss of catalytic activity.

Synthesis of new benzoxazaphosphinine/benzoxazaphosphole/ diazaphosphaphenalene 2-sulfides were accomplished by the reaction of Lawesson's reagent (LR) with 4-bromo-2-[(phenylamino) methyl]phenol (1a), 4-bromo-2-[(4-chloro/bromo/methoxy/methylphenyl-amino)methyl]phenol (1b-e), 4-bromo-2-[(benzylamino)methyl]phenol (1f), 2-amino-4-chlorophenol (2a)/2-amino-4-methylphenol (2b), 1,8-diaminonaphthalene (3) respectively in anhydrous toluene. Products 4a-f, 5a-b and 6 were characterized by IR, 1H, 13C, 31P NMR and Mass spectra. Copyright Taylor & Francis Group, LLC.
