High-Efficiency Dibromination of Organic Compound in Microfluidic Channel of SI Pillar Array Directly Coated with Iron Catalys

In a microfluidic device developed using a Si micro-pillar array directly coated with an iron catalyst, 4,8-dibromo-1-hydroxy-2-naphthaldehyde was catalytically synthesized with high efficiency. This represents the first dibromination of the organic compound in a microfluidic device. Typical beaker synthesis of the compound takes one day at 50 °C, but the method proposed here was performed at uncontrolled room temperature (23 °C), while reducing the reaction time to about 1 sec.
