1-Methyl and 1-allyl-2,4,6-triphenylpyridinium cations react with aromatic aldehydes at the α-CH2 to give aldol products (7) and (8).The allyl adducts (8) were thermally converted into aldehydes and ketones, whereas thermolysis of (7) took a variety of courses.Zwitterions from 1-methylpyridinium cations were also added Michael-fashion to activated carbon-carbon double bonds.
