Abstract:Reported is the reaction of a series of iron(II) bisphosphine complexes with PH 3 in the presence of NaBAr F 4 [where BAr F 4 = tetrakis(3,5-bis(trifluoromethyl)phenyl)borate]. The iron-(II) bisphosphine reagents bear two chlorides or a hydride and a chloride motif. We have isolated six different cationic terminal-bound PH 3 complexes and undertaken rigorous characterization by NMR spectroscopy, single crystal X-ray diffraction, and mass spectrometry, where the PH 3 often remains intact during the ionization p… Show more
