[SiP3(dmpe)FeCl][Cl] (2-Cl) and SiP3(dmpe)Fe (4) (SiP3 = MeSi(CH2PMe2)3, dmpe = Me2PCH2CH2PMe2) were prepared in the same manner as 1 and 3 but with lower yields because of competitive ligand rearrangement reactions that gave byproduct of trans-(dmpe)2FeCl2 and (dmpe)5Fe2 (5). [tSiP3(dmpm)FeH][A] (6) was prepared from the reaction of 3 with weak acids (HA), and the pKa of 6 was established to be approximately 25. Attempts
