Abstract

Treatment of Fe 2(pdt)(CO) 4(dppv) (1) with aryldiazonium salts affords the 34 e - adducts [Fe 2(pdt) (ν-N 2Ar)(CO) 4(dppv)] + (pdt 2- = 1,3-propanedithiolate, dppv = cis-C 2H 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 3S 2] + and Fe 2(pdt)(CO) 4(dppbz) was found to give [Fe 2(pdt)(CO) 4(dppbz)] + as well as Me 2S and Me 2S 2 (dppbz = 1,2- bis(diphenylphosphino)benzene).
