给出了有机氟硒化合物混合物的77 Se、19 F {1H}位移相关二维NMR测量结果，用于归属77 Se和19 F共振。以区域异构体氟（苯硒基）烯BuCF C（SePh）R和RCF C（SePh）Bu（R = Me、Et和nPr）以及具有手性芳基Ar* 和PhSeCH CF 2的非对映体对EtCHFCH（SeAr*）Et为模型化合物进行了研究。测量了J（Se，F）偶合常数从41下降到4 Hz的~（77）Se，~（19）F相关峰。版权所有© 2002年约翰威利父子有限公司。
77Se,19F{1H} shift correlated two‐dimensional NMR measurements on mixtures of organofluoroselenium compounds are presented for assignment of the 77Se and 19F resonances. The regioisomeric fluoro(phenylseleno)alkenes BuCFC(SePh)R and RCFC(SePh)Bu with R = Me, Et and nPr and the diastereomeric pair EtCHFCH(SeAr*)Et with a chiral aryl group Ar* and PhSeCHCF2 were investigated as model compounds. 77Se,19F correlation peaks resulting from J(Se,F) coupling constants from 41 down to 4 Hz were measured.
