- Sulfonic acid supported on hydroxyapatite-encapsulated-γ-Fe 2O3 nanocrystallites as a magnetically separable catalyst for one-pot reductive amination of carbonyl compounds
-
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 using Lawesson's reagent
-
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.
