首次采用反相高效液相色谱法(RP- HPL C)直接测定1-溴代萘分别与片呐酮碳负离子和苯乙酮碳负离子在铁硫簇合物(Et4 N) 2 [Fe4 (SPh) 1 0 ]催化引发下的SRN1反应产物3,3-二甲基- 1- (1-萘基) - 2 -丁酮和2 - (1-萘基) - 1-苯乙酮的含量差异.以甲醇/四氢呋喃/水为流动相,经C1 8色谱柱分离,在2 5 4 nm检测波长下,最低检测限分别为0 .0 0 4 mg/ L 和0 .0 11mg/ L,线性方程分别在0 .0 12 mg/ L～1.4 m g/ L 和0 .0 11mg/ L～0 .8mg/ L 范围内具有良好的线性关系,相关系数分别为0 .9999和0 .9996 .
The first direct determination of 1-bromonaphthalene with nadoxone and acetophenone carbanion in the presence of iron-sulfur cluster (Et4N) 2 [Fe4 (SPh ) 1 0] SRN1 reaction product catalyzed reaction content of 3,3-dimethyl-1- (1-naphthyl) -2-butanone and 2 - (1-naphthyl) -1-acetophenone The lowest detection limits were 0.054 mg / L and 0.011 mg / L respectively at a detection wavelength of 254 nm with methanol / tetrahydrofuran / water as the mobile phase and separated on a Cl 8 column. The linear equation Respectively, with a good linear relationship in the range of 0.012 mg / L ~ 1.4 mg / L and 0.11 mg / L ~ 0.8 mg / L with the correlation coefficients of 0.9999 and 0.9996, respectively.
