Several tertiary arsine sulphides have been prepared by the action of sulphur on tertiary arsines in C6H4Cl2-o at high temperature. AsPh3 and AsMePh2 react with S2Cl2 to produce AsPh3Cl2 and AsMePh2Cl2, respectively, and no tertiary arsine sulphide, contrary to an earlier report. The reversible transfer of sulphur from AsPh3S to AsMePh2 occurs readily in solution. Methyldiphenylarsine sulphide, a liquid
通过硫在高温下在C 6 H 4 Cl 2 - o中的硫对叔action的作用,已经制备了几种叔rs化硫。ASPH 3和AsMePh 2带S反应2氯2以产生ASPH 3氯2和AsMePh 2氯2分别,并且没有第三胂硫化物,相反到较早的报告。硫从AsPh 3 S到AsMePh 2的可逆转移很容易在溶液中发生。甲基二苯基ar硫醚,在室温下为液体,与P(NMe)形成1:1的结晶加合物2) 3加合物的O的结构已经从1个913独立衍射仪数据确定和细化至最终ř 0.050因子。晶体是正交晶体,空间群为Pbca, a = 11.866(3), b = 17.134(7), c = 22.657(2)Å, Z =8。除正常范德华力之外,这两个组件之间没有相互作用。势力。对于As–S 2.069(3),As–C(甲基)1.932(10),As–C(苯基)1.947(平均),P–O 1.461(7)和P–N 1
