A Convenient Synthesis of N-Vinylpyridinium Perchlorate and a Study of N-Vinylpyridinium Cations as Michael Reaction Acceptors
Katritzky, Alan R.,Rubio, Olga
, p. 4017 - 4021 (2007/10/02)
The titel compound is easily prepared from 1-(2-bromoethyl)pyridinium bromide and sodium hydroxide. 1-Vinylpyridinium and 1-vinyl-2,4,6-triphenylpyridinium cations add N, S, and C nucleophiles in Michael-type reactions.
Carbon-Nitrogen Bond Cleavage in ?-Radicals derived by Reduction of N-Benzyl- and N-Allyl-pyridinium Salts
Grimshaw, James,Moore, Shirley,Thompson, Norris,Trocha-Grimshaw, Jadwiga
, p. 783 - 784 (2007/10/02)
Certain 1-alkyl-2,4,6-trisubstituted pyridinium salts form ?-radicals by electrochemical reduction which are stable in dimethylformamide on the time scale of cyclic voltammetry, whereas the corresponding 1-benzyl and 1-allyl compounds undergo carbon-nitrogen bond cleavage at measured rates which are dependent on the size of the 2,6-substituents.
Heterocycles in Organic Synthesis. Part 42. Preparation of Azides, Phthalimides, and Sulphonamides from Primary Amines
Katritzky, Alan R.,Liso, Gaietano,Lunt, Edward,Patel, Ranjan C.,Thind, Sukhpal S.,Zia, Abid
, p. 849 - 851 (2007/10/02)
N-Alkyl and N-benzyl substituents are displaced from 2,4,6-triphenylpyridinium cations by nucleophilic azide, phthalimide, succinimide, and sulphonamide anions.This enables the conversion of primary alkyl- and benzylamines into azides, and primary (with potential for inversion or labelling) and secondary amines.
