Isotope Effects in the p-Tolylation of Pyridine

Article abstract of DOI:10.1246/bcsj.54.2535

p-Toluoyl peroxide, p-iodotuluene, and di-p-tolyl sulfone, sulfoxide, and sulfide were photolyzed in an equimolar pyridine-pyridine-d5 mixture to give rise to isomeric p-tolylpyridines (α, β, and γ) and their deuterated compounds.Isotopic distribution ratios (Y_H/Y_D) in the isomeric products were determined to be slightly larger than unity.
