  1H,13C and15N NMR and IR studies of halogen-substituted tetrazolo[1,5-a]pyridines

  摘要：

  The tetrazole-azide tautomerization of some halogen-substituted tetrazolo[1,5-a]pyridines was examined by IR spectroscopy at ambient temperature and by H-1,C-13 and N-15 NMR spectroscopy at various temperatures. The tetrazolopyridines can exhibit equilibrium between the azide and the tetrazole forms. For some of them slow exchange occurs on the NMR time-scale, such that it is possible to estimate equilibrium constants. The position and nature of the substituent in the pyridine ring result in stabilization or destabilization of the tetrazole form and exert a strong influence on the values found for the equilibrium constants. A saturation transfer experiment was carried out for 5-bromotetrazolo[1,5-a]pyridine and the rate constants were estimated. Moreover, based on the van't Hoff equation, the enthalpy Delta H degrees and entropy Delta S degrees for the tautomerization were calculated. Ab initio calculated energies and charge distribution are in good agreement with differences observed in the tetrazole-azide equilibrium constants. Copyright (C) 1999 John Wiley & Sons, Ltd.

  Pyridine ring substituted (1H-1,2,3-triazol-1-yl)pyridines were prepared and found to have insecticidal utility. 2-Chloro-6-(1H-1,2,3-triazol-1-yl)pyridine, for example, was prepared from 2-azio-6-chloropyridine and methyl propiolate by sequential condensation, hydrolysis, and decarboxylation and found to control aster leafhoppers.

  取代了吡啶环的(1H-1,2,3-三唑-1-基)吡啶被制备出来，并发现具有杀虫效用。例如，2-氯-6-(1H-1,2,3-三唑-1-基)吡啶是通过顺序缩合、水解和脱羧反应从2-氮杂-6-氯吡啶和丙烯酸甲酯制备而成，发现可以控制紫菜叶蝉。
