许多有机磷化合物的核磁共振已有报道。本文研究二烷氧基膦酰乙酸酯化合物(?)(1～17)的~1H、~(31)P 及~(13)CNMR 谱,观察了 P—O—C 键的受阻转动,获得了~2J_(CCP),~3J_(CCOP)和 J_(HP)值。对鉴定其它磷化物的结构有一定意义。化合物1,3虽有同核二
Nuclear magnetic resonance of many organophosphorus compounds has been reported. In this paper, the ~ 1H, ~ (31) P and ~ (13) CNMR spectra of the dialkoxy phosphonoacetate ester compounds (1-17) were investigated. The hindered rotation of the P-O-C bond was observed. ~ 2J_ (CCP), ~ 3J_ (CCOP), and J_ (HP) values. The identification of other phosphide structure has some significance. Although compounds 1 and 3 have the same nuclear two
