nzo[d,g][1,3,6,2]dioxathiaphosphocin 6-oxides are described. Their IR, 1H, 13C, and 31P NMR spectral characteristics are reported. Long-range couplings (2JPOC and 3JPOCC) between phosphorus and carbons were observed. An X-ray diffraction analysis of a crystal of 2,10-dichloro-6-ethoxydibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-oxide indicated a boat-chair conformation to the dioxathiaphosphocin ring
描述了 2,10-dichloro-6-alkoxydibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-氧化物的合成。报告了它们的 IR、1H、13C 和 31P NMR 光谱特征。观察到磷和碳之间的长程耦合(2JPOC 和 3JPOCC)。2,10-dichloro-6-ethoxydibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-oxide 的晶体的 X 射线衍射分析表明具有磷酰基的 dioxathiaphosphocin 环的船椅构象轴向的氧和赤道方向的乙氧基。该分子具有穿过硫、磷、磷酰氧和乙氧基的镜面对称性。
