Several novel 2,4,8,10-tetra-t-butyl-6-substituted dibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-oxides were synthesized in high yield by cyclocondensation of 2,2′-thiobis(2,4-di-t-butylphenol) with phosphorus oxychloride in the presence of triethylamine and a catalytic amount of dimethylaminopyridine (DMAP) in dry toluene followed by in situ reaction with different bulky phenols/thiophenols under the
几种新的2,4,8,10-四-吨-丁基-6-取代的二苯并[ d,克] [1,3,6,2] dioxathiaphosphocin -6-氧化物是由2,2-环缩合以高产率合成“硫代双(2,4-二-吨丁基苯酚)在三乙胺存在下和在无水甲苯,随后二甲基氨基吡啶(DMAP)催化量的磷酰氯在原位用相同的反应条件下不同笨重苯酚/苯硫酚反应。通过分析,IR,多核NMR研究证实了合成化合物的结构。评估了它们对金黄色葡萄球菌,大肠杆菌,黑曲霉和尖孢镰刀菌的抗菌和抗真菌活性。, 分别。其中一些对这些微生物表现出中等活性。
