Vicarious nucleophilic substitution of pyridines via their dicyanomethylide derivatives
Itoh,Nagata,Okada,Ohsawa
, p. 220 - 222 (1993)
Vicarious nucleophilic substitution of pyridinium 1-dicyanomethylides with 1-chloromethyl phenyl sulfone gave corresponding 4-substituted derivatives. The dicyanomethylene group was readily eliminated via radical reaction to afford 4-phenylsulfonylmethylp
