Abstract Vicariousnucleophilicsubstitution (VNS) by dichloroacetate and other reagents has been applied in good yield to various ortho-substituted nitrobenzenes including 2-nitrotoluene and 2-nitro ethylbenzene. For alkyl nitrobenzenes, ease of VNS increased para < ortho < meta and methyl < ethyl < iso-propyl. Formation of chlorine-free products upon VNS by methyl dichloroacetate suggests the involvement
