1-(2,5-Dimethoxy-4-nitrophenyl)piperidine
Molbank, 2023 Treatment of the non-purified mixture of dinitro isomers obtained from the nitration of 1,4-dimethoxybenzene with piperidine led to the isolation of novel but minor adduct, 1-(2,5-dimethoxy-4-nitrophenyl)piperidine (2b) in 15% yield.

Mechanisms of Nucleophilic Aromatic and Hetero-aromatic Substitution. Recent Developments
CHIMIA, 1980 There are now at least five well defined mechanisms of nucleophilic aromatic and heteroaromatic substitution. Three of them, the SNAr, the benzyne and the SN1 mechanism, have been known for a long time, whereas the SRN1and the SN (ANRORC) mechanisms are
