Abstract
From 3,5-dinitrobenzoyl chloride,the corresponding benzaldehyde was isolated after reduction.The procedure to obtain 3-hydroxy-5-nitrobenzaldehyde under the basic condition necently reported in the literature has been modified in this investigation.The ratios of oxime to substrate were optimized from 2/1 to 1/1.The amount of oxime is reduced to half,and the yield is 90%.
