Henrick, C. A. published the artcilePyridinium ylides in synthesis. II. Acylation and the synthesis of β-dicarbonyl compounds, Safety of 1-(Cyanomethyl)pyridin-1-ium chloride, the publication is Australian Journal of Chemistry (1967), 20(11), 2455-65, database is CAplus.
The acylation of N-pyridinium ylides with acid chlorides or anhydrides yields C-acylated ylides which may be reductively cleaved to yield β-diketones or β-keto esters, depending on the starting materials. The uv, ir, and N.M.R. spectra of the ylides are discussed. 34 references.
