Reaktionsschritte

A mixture of 2,4,5 trimethoxy phenyl propene (1 mmol), N-bromosuccinimide (1.2 mmol), water (14 ml), cetyltrimethyl ammonium bromide (0.3 mmol) were taken in a 100 ml round bottom flask fitted with a condenser. The flask was shaken well and placed inside the monomode microwave oven and irradiated (220 W, 200° C.) for 12 minutes in parts. After completion of reaction, the reaction mixture was worked up as in example-1 to provide the corresponding 2-(2,4,5 trimethoxy phenyl)propionaldehyde (43% yield) whose spectral data matched with that mentioned in example-1.
