A novel series of O, O′, O″, O”′-tetraaryldithioimidophonates [(ArO) 2 PS] 2 NH 4 were synthesized by the reaction of O, O,-diaryl phosphorochlorothionates 2 and diarylphosphonothioic amide under a strong basic condition. The key intermediates 2a ∼ 2g were prepared from thiophosphyl chloride and substituted phenols under phase transfer catalysis conditions for the first time. These teteraaryl dithioimidophonates
通过O,O,-二芳基氯硫代磷酸酯2和二芳基硫代膦酰胺在强碱性条件下反应合成了一系列新型O,O',O",O"'-四芳基二硫代亚氨基膦酸酯[(ArO)2PS]2NH4。以硫代磷酰氯和取代酚为原料,在相转移催化条件下首次制备了关键中间体2a~2g。这些四芳基二硫代亚氨基膦酸酯对来自硫酸盐溶液的 Zn 2 + 比 Fe 3 + 显示出高选择性。还讨论了取代基对标题化合物的 31 P NMR 的影响。
