Highly regioselective reactions of pyridinium ylides with tetracyanoethylene occur via an AdN-E mechanism to form Z-isomers of 3-aroyl-3-(1-pyridinio)-1,1,2-tricyano-2-propenides-1, corresponding in structure to 1,4-ylides with maximum charge s
REGIO-AND STEREOSELECTIVITY OF THE REACTIONS OF PYRIDINIUM AND PICOLINIUM SALTS AND YLIDS WITH NITRILES CONTAINING A NUCLEOFUGIC GROUP
Shestopalov, A. M.,Litvinov, V. P.,Sharanin, Yu. A.,Aitov, I. A.,Rodinovskaya, L. A.
, p. 835 - 838 (1991)
The reaction of pyridinium, 2-picolinium, and 3-picolinium ylids with tetracyanoethylene, ethoxymethylenemalononitrile, and (dimethylthio)methylenecyanamide in the presence of organic bases proceeds regio- and stereoselectively to give substituted pyridin
REGIOSELECTIVITY IN THE REACTION OF AZINIUM SALTS AND YLIDES WITH TETRACYANOETHYLENE

The reactions of pyridinium, picolinium, and quinolinium salts and ylides with tetracyanoethylene have been found to be regioselectivive.Reaction of azinium salts with tetracyanoethylene in aqueous methanol affords azinium tricyanoethylenolates, but pyrid
