Easily available N-cyanomethyl-N-methyl-2-arylpyrrolidinium salts treated with a base undergo ring expansion ([1,2]-Stevens rearrangement) with formation of new cis,trans-3-aryl-2-cyano-1-methylpiperidines. All reactions were performed under mild conditions and usually proceed in good yield. cis-Diastereoisomers of the products were isolated. The products and the starting intermediate quaternary salts
