Treatment of Fe(2)(pdt)(CO)(4)(dppv) (1) with aryldiazonium salts affords the 34e(-) adducts Fe(2)(pdt)(μ-N(2)Ar)(CO)(4)(dppv) (pdt(2-) = 1,3-propanedithiolate, dppv = cis-C(2)H(2)(PPh(2))(2)). Under some conditions, the same reaction gave substantial amounts of 1, the product of electron-transfer. Consistent with the influence of electron transfer in the reactions of some electrophiles with Fe(I)Fe(I) dithiolates, the reaction of Me(3)S(2) and Fe(2)(pdt)(CO)(4)(dppbz) was found to give Fe(2)(pdt)(CO)(4)(dppbz) as well as Me(2)S and Me(2)S(2) (dppbz = 1,2-bis(diphenylphosphino)benzene).
用芳基重氮盐处理Fe(2)(pdt)(CO)(4)(dppv) (1)可得到34e(-)加合物Fe(2)(pdt)(μ-N(2)Ar)(CO)(4)(dppv)（pdt(2-) = 1,3 - 丙二硫醇盐，dppv = 顺式 - C(2)H(2)(PPh(2))(2)）。在某些条件下，相同反应会生成大量电子转移产物1。与某些亲电试剂与Fe(I)Fe(I)二硫醇盐反应中电子转移的影响一致，发现Me(3)S(2)与Fe(2)(pdt)(CO)(4)(dppbz)反应生成Fe(2)(pdt)(CO)(4)(dppbz)以及Me(2)S和Me(2)S(2)（dppbz = 1,2 - 双（二苯基膦基）苯）。
