Methyl Deuteration Reactions in Vinylporphyrins: Protoporphyrins IX, III, and XIII
Base-catalyzed deuteration of the methyl groups in protoporphyrin IX dimethyl ester (1) proceeds with differential deuteration; rate of deuteration, as measured by NMR spectroscopy of reaction products, follows the order 3-Me > 1-Me >5-Me >8-Me.A simple q

Neighboring Group Participation in the Pyrrole Series
With use of proton and carbon-13 NMR spectroscopy of deuterium- and carbon-13-labeled substrates, the transformation of certain (2-hydroxyethyl)pyrroles (4, 18, 21) into the corresponding (2-haloethyl)pyrroles (using thionyl chloride/pyridine or triphenyl
