2,4,8,10-四卤代-6-硫-12-H-双苯并[d,g][1,3,2]-二氧磷杂八环的1H和13CNMR研究
A 1H and 13C NMR Study on 2,4,8,10-tetrahalogen-6-thio12H-dibenzo-dioxaphosphocin
【摘要】 通过2D NMR技术对5个2,4,8,10-四卤代-6-硫-12-H-双苯并[d,g][1,3,2]-二氧磷杂八环的1H和13C NMR信号进行了准确的归属,获得了所有芳环碳原子的P-C和部分质子的P-H偶合常数,3/9位质子的5JPH属于折线型偶合,偶合常数为0.9~1.0 Hz.
【Abstract】 The 1H and 13C NMR signals of 2,4,8,10-tetrahalogen-6-thio-12H-dibenzo-dioxaphosphocins were assigned with 2D NMR techniques.The P-C coupling constants for all aromatic carbons and the P-H coupling constants were obtained,among which the 5JPH coupling constants was in the range of 0.9~1.0 Hz for protons at C-3/C-9(zigzag coupling).
