Preparation of 4-Nitrobenzoyl chloride: At first, add p-nitrobenzoic acid and phosphorus pentylchloride into the oil bath with heating. After the reaction, you can recycle trichlorooxyphosphorus through vacuum distillation. And then via vacuum distillation you can obtain the crude of this product. Next, melt the crude into liquld and then add carbon tetrachloride. You get the desired product through filtration, cooling and crystallization.

Uses of 4-Nitrobenzoyl chloride: it can react with 2-hydroxy-1,2-diphenyl-ethanone to get a-(4-nitro-benzoyloxy)-deoxybenzoin. This reaction will need reagent pyridine. The reaction time is 15 minutes by heating. The yield is about 62%.
