3-Carboxy-5-nitrophenylboronic acid Use and Manufacturing
The 7.5g between 5-carboxyphenylboronic acid(45.2mmol) by adding 25 ml of concentrated sulfuric acid, under rapid stirring state by adding 25 ml fuming nitric acid, ice water bath cooling. Stirring the reaction 15 min evacuation de-ice water bath, to continue reaction 15 min. In ice water into the reaction liquid, precipitate, filtering, washing 5 times, re-crystallization with water, to obtain white solid 3-nitro-5-carboxyl phenylo boric acid 6.01g, yield 63.0percent ; the 1.50g3-carboxy-5-nitro-phenylboronic acid (7.1mmol), 20 ml methanol, 10percent Pd/C0 . 2g by adding 50 ml in three-necked bottle, catalytic hydrogenolysis 6h. Filtered to remove palladium-carbon, the filtrate is evaporated to dryness, to obtain white powder solid 3-amino-5-carboxyl phenylo boric acid 1.25g, yield 97.1percent.
