organic chemistry - Selective reduction of nitro group to …

WebAromatic nitro compounds are readily reduced by SnCl A 2 ⋅ 2 H A 2 O in alcohol or ethyl acetate or by anhydrous SnCl A 2 in alcohol where other reducible or acid sensitive groups such as aldehyde, ketone, ester, cyano, halogen, and O -benzyl remain unaffected. This point is depicted in following diagram as two examples given in Ref.1: The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds. aspek yang terdapat dalam geostrategi yakni
