NMR study of C- and N-trimethylsilylazole derivatives

C- and N-trimethylsilylazole derivatives were studied by 1H, 13C and 29Si NMR spectroscopy. Degenerated prototropic tautomerism of 4-trimethylsilylpyrazole in methanol and the silylotropy of 1-trimethylsilyl-4-methylpyrazole in a neat liquid were investigated for the first time. 3- and 5-tautomers of 3(5)-methylpyrazole in a ratio of 54:46 were found in methanol by use 13C NMR spectroscopy (Tc = 230 K, ΔGc ≠ = 10 kcal mol-1).
