Syntheses Using Pyridinium Salts

Angewandte Chemie International Edition in English, 1963
AbstractThis review discusses syntheses leading to a new type of N‐vinylpyridinium salts, to novel anionocyanines, to aminophenazines and alloxazines, as well as to (aza‐) dehydroquinolizinium, acridizinium, and morphanthridizinium salts. In addition, Mannich reactions and aminoalkylations at active methylene groups of cycloimmonium salts, and their ...

The synthetic potential of pyridinium salt photochemistry

Photochemical & Photobiological Sciences, 2008
The discovery in the 1970s by Kaplan, Wilzbach and Pavlik that pyridinium salts undergo a unique cyclization reaction to produce bicyclic-aziridines was virtually unrecognized for nearly three decades. It was only comparatively recently that the process was explored in more detail and its synthetic potential exploited.
