The reactions of mono-, di-, and trichloronitrobenzenes with 1-methylpyrrolidine under high pressure gave products of demethylation and ring-opening through a quaternary pyrrolidinium chloride intermediate formed by the SNAr reaction.On the other hand, the reactions with 1-methylpiperidine and 4-methylmorpholine gave only demethylation products.The selectivities of the resctions of 1-methylpyrrolidine with these chloronitrobenzenes were found to be effected by the neighboring substituent to the pyrrolidinium group.
