solutions. The reactions of MR3(M = P, As, or Sb) with ICl and ICl3 also give rise to highly conducting adducts in acetonitrile but the conductometric titration graphs indicate that these reactions are complex. Some of the adducts (PPh3Cl3I, AsPh3Cl3I, and AsPh3Cl5I) have been obtained as crystalline solids.
用卤素和卤素间化合物对PPh 3 Cl 2和AsPh 3 Cl 2的电导滴定表明,该反应很简单,导致形成MPh 3 Cl 2 X 2(M = P或As; X 2 = Br 2,I 2,ICl或IBr)和MPh 3 Cl 5 I(M = P或As)的
乙腈溶液。加合物的高摩尔电导表明它们的配方为MPh 3 Cl + ClX 2 –和MPh 3 Cl + ICl 4 –分别。从
乙腈溶液的紫外光谱已经鉴定出存在的多卤离子。MR 3(M = P,As或Sb)与ICl和ICl 3的反应也会在
乙腈中产生高传导性加合物,但电导滴定图表明这些反应很复杂。已获得一些加合物(PPh 3 Cl 3 I,AsPh 3 Cl 3 I和AsPh 3 Cl 5 I)作为结晶固体。
