本文报道了16个苯基-(1和3)和苯基硫代磷酰基(2)衍生物的合成。~(13)C和~(17)O NMR数据灵敏地反映了磷酰基取代基中由X/Y向P的pπ-dπ反馈所引起的电子密度变化,导出了16个磷酰基取代基的塔夫脱常数σ1和σR 0。
Abstract The syntheses of 16 phenyl- (1 and 3) and phenylthiophosphoryl (2) derivatives are described. The 13C and 17O NMR data sensitively reflect electron density changes in the phosphoryl substituents caused by pπ–dπ back-donation from X/Y to P. Taft constants σ1 and σR 0 were derived for 16 phosphoryl substituents.
