测定梭曼四种立体异构体的NMR研究

NMR STUDY ON DETERMINATION OF THE FOUR STEREOISOMERS OF SOMAN

本文采用手性位移试剂、Eu(TFC)和Eu(HFC)_3对梭曼的立体异构体测定作了研究。结果表明,在苯中梭曼的立体异构体与其中的Eu(HFC)_3形成的络合物显示较大的^(19)F化学位移差,并能同时进行测定。该法尚未见报道。

The dctermina of four of soman has been studied by NMR chiral shift reagents Eu ( TFC) 3 and Eu ( MFC) 3. It was found that the complexes of soman with Eu ( HFC)3 in C6D6 show larger 19F NMR shift difference, which can been used for the simultaneous qantitaivc determination of the four stcrcoisomcrs of soman.
