Abstract
Urea-hydrogen peroxide complex (UHP) has been found to be an efficient oxidizing agent for the oxidation of various alkyl benzenes/naphthalene/tetralin under microwave irradiation in solvent-free conditions.
Key words
alkylbenzenes - urea-hydrogen peroxide complex - benzylic oxidations - solvent-free conditions - microwave activation

General Procedure: Substrate (1 mmol) and UHP (15 mmol) were added to a borosil beaker (50 mL). The mixture was stirred properly and then irradiated in a microwave oven for an appropriate time (Table
[1 2 Cl2 (3 × 15 mL). The combined methylene extracts were washed with H2 O and dried over anhyd Na2 SO4 . The product obtained after removal of the solvent under reduced pressure was crystallized from an appropriate solvent.2 O2 .
30 All reactions were carried out in an unmodified domestic microwave oven BPL BMO 800T having maximum output of 800 W operating at 2450 MHz.
