We present a two-step, general synthesis of N-arylputrescines and cadaverines, by cesium carbonate mediated alkylation of anilines with Ï-chloronitriles and subsequent reduction. The cesium-mediated alkylation shows remarkable selectivity towards the monoalkylation product. The method is straightforward and leads to satisfactory global yields.

omega-arylaminonitriles promoted by polyphosphoricacid (PPA) esters. 1-Aryl-2-iminopyrrolidines were easily prepared from the acyclic precursors employing a chloroformic solution of ethyl polyphosphate (PPE). The use of trimethylsilyl polyphosphate (PPSE) in solvent-free conditions allowed for the synthesis of 1-aryl-2-iminopiperidines and hitherto unreported 1-aryl-2-iminoazepanes. The cyclization reaction involves
