A novel representative of sodium 3,4,5-triaryl-1,2-diphosphacyclopentadienide containing a chloro substituent in the -position of the aryl groups was obtained with a high yield based on the reaction of tributyl(1,2,3-triarylcyclopropenyl)phosphonium bromide and sodium polyphosphides. Further reaction of sodium 3,4,5-tris(3-chlorophenyl)-1,2-diphosphacyclopentadienide with [FeCp(η-CHCH)][PF] complex gives a new 3,4,5-tris(3-chlorophenyl)-1,2-diphosphaferrocene. The electrochemical properties of 3,4,5-tris(3-chlorophenyl)-1,2-diphosphaferrocene were studied and compared to 3,4,5-tris(4-chlorophenyl)-1,2-diphosphaferrocene. It was found that the position of the chlorine atom on the aryl fragment has an influence on the reduction potential of 1,2-diphosphaferrocenes, while the oxidation potentials do not change.
基于三丁基(1,2,3-三芳基环丙烯基)溴化鏻与多硫化钠的反应，高产率地得到了一种新型的3,4,5-三芳基-1,2-二磷杂环戊二烯钠衍生物，其芳基的α位含有氯取代基。3,4,5-三(3-氯苯基)-1,2-二磷杂环戊二烯钠与[FeCp(η-C₂H₄)][PF₆]配合物进一步反应得到一种新的3,4,5-三(3-氯苯基)-1,2-二磷杂二茂铁。研究了3,4,5-三(3-氯苯基)-1,2-二磷杂二茂铁的电化学性质，并与3,4,5-三(4-氯苯基)-1,2-二磷杂二茂铁进行了比较。结果发现，芳基片段上氯原子的位置对1,2-二磷杂二茂铁的还原电位有影响，而氧化电位不变。
