Abstract
AbstractThe cover picture shows the mechanistic scheme of the synthesis of imidazo[1,5‐a]pyridinium salts from phenylchlorodiazirine and 2‐pyridyl Schiff bases. The carbene produced by thermolysis of the diazirine reacts with the pyridyl Schiff base to give two different ylide species, which are detected by laser flash photolysis. However, a single product is formed in a nearly quantitative yield and is easily separated from the reactants since it precipitates in nonpolar solvents. Colour code: blue = N, red = Cl, yellow = alkyl or aryl substituent, green = phenyl group. Details are discussed in the article by R. Bonneau and P. Guionneau on p. 5459 ff.
