α-(2-苯并噻唑氧基)烃基膦酸酯的波谱性质

Spectra of α-(benzothiazol-2-yl-oxy)-alkyl phosphonate

通过α－（２－苯并噻唑氧基）烃基膦酸酯的１ＨＮＭＲ，１３ＣＮＭＲ谱的分析，讨论了中心磷原子对α烷氧基和烷基质子的裂分以及Ｐ－Ｏ－Ｃ旋转受阻现象。分析了化合物（１－８）的质谱特征。

The spectra of α (benzothiazol 2 yl oxy) alkyl phosphonate were reported.The restricted rotation of P O C and the influence of the phosphor atom on the splitting of α alkoxy proton and alkyl proton in 1HNMR及 13 CNMR were discussed.The MS spectra were interpreted.
