摘要
通过双 - (2 -羟基 -氯代苯基 )甲烷 2与 P4 S10 在三乙胺存在下的关环反应 ,得到了6 -硫 - 6巯基 - 12 H-氯代双苯并 [d,g][1,3,2 ]-二氧磷杂八环三乙胺盐 3,后者与卤代烷酯化得到了一系列 6 -硫 - 6 -烷硫基 - 12 H-氯代双苯并 [d,g][1,3,2 ]-二氧磷杂八环 4 ,测试并讨论了它们的 1H和 3 1P NMR数据。初步生物试验结果表明化合物 4对黄瓜霜霉病菌具有较好的抑制活性。
Three new triethylamine salts of 6 mercapto 12 H chlorosubstituted dibenzo [ d,g ][1,3,2] dioxaphosphocin 6 sulfides 3 were prepared by the cyclic reaction of bis(2 hydroxy chlorophenyl) methane 2 with P 4P 10 in the presence of triethyl amine. A series of novel compounds of 6 alkylthio 12 H chlorosubstituted dibenzo [ d,g ][1,3,2] dioxaphosphocin 6 sulfides 4 were synthesized in good yields for the first time from 3 and alkyl halides. 31 P and 1H NMR spectra of 4 were reported and discussed. 4 show good fungistatic activities against Pseudoperonospora cubensis in preliminary bioassays.
