Novel 6-substituted 2,10-dichloro-4,8-dinitrodibenzo[d,g][1,3,6,2]dioxathiaphosphocin-6-oxides 4 were synthesized by reacting 5,5′-dichloro-3,3′-dinitro-2,2′-dihydroxydiphenyl sulfide (2) with different aryl phosphorodichloridates, trichloromethylphosphonic dichloride and O-2-chloroethyl phosphoryldichloride (3) in the presence of triethylamine at 55–60°. Some of these compounds are prepared by reacting
通过5,5'-dichloro-3,3'反应合成了新颖的6-取代的2,10-dichloro-4,8-dinitrodibenzo [ d,g ] [1,3,6,2] dioxathiaphosphocin-6-氧化物4 -二硝基-2,2'-二羟基二苯硫醚(2)与不同的芳基二氯膦酸酯,三氯甲基膦二氯和O-2-氯乙基磷酰二氯(3)在三乙胺存在下于55-60°混合。这些化合物中的一些化合物是通过将一氯化物2,6,10-三氯-4,8-二硝基二苯并[ d,g ] [1,3,6,2]二氧杂ia磷-6-氧化物(5)与取代基原位反应制得的酚和硫醇。通过将2与三氯氧化磷缩合来制备5。在1二苯并二氧杂硫杂膦球蛋白部分的H nmr化学位移表明溶液中存在多个以上的构象异构体。但是,不能完全消除每个实例中不止一个构象体的存在。有趣的是图4d上氧化成12-砜由H 2 Ó 2在乙酸介质仅产生12亚砜6A。讨论了ir,1
