Synthesis of a new carbbenzyloxymethylenetriparatolylphosphorane ylide and study of its reaction with mercury(II) halides: Spectral and structural characterization
techniques. The reactions of the title ylide with mercury(II) chloride, mercury(II) bromide and mercury(II) iodide in equimolar ratios using dry methanol as solvent have yielded [BTPY · HgCl2]2 (1), [BTPY · HgBr2]2 (2) and [BTPY · HgI2]2 (3), respectively. Single crystal X-ray analysis of 2 reveals the presence of a centrosymmeteric dimeric structure containing the ylide and HgBr2. The analytical data
合成了一种新的羰基苄氧基亚甲基三对甲苯基正膦基膦(BTPY)(对甲苯基)3 PCHCOOCH 2 C 6 H 5 },并通过元素分析和各种光谱技术对其进行了表征。以干燥甲醇为溶剂,以等摩尔比计的标题内鎓盐与氯化汞(II),溴化汞(II)和碘化汞(II)反应生成了[BTPY·HgCl 2 ] 2(1),[BTPY·HgBr 2 ] 2(2)和[BTPY·HgI 2 ] 2(3)。单晶X射线分析图2揭示了含有叶立德和HgBr 2的中心对称二聚体结构的存在。后一种化合物的分析数据,IR和1 H,13 C和31 P NMR数据与1和3相似,表明结构相似。理论研究表明,对于所有三种化合物,在每种情况下,观察到的化合物2的反式结构比可能的顺式结构更稳定。
