摘要:
The reaction of the dialkyliron complex [Fe(CH2SiMe3)(2)(MesBIP)] ((BIP)-B-Mes = 2,6-bis((N-mesityl) acetimidoyl) pyridine) with protic acids (HY) of different strengths (Y = C6F5O, CF3CO2, Cl, CF3SO3) invariably leads to the cleavage of both Fe-C bonds, independent of the Fe/HY ratio used (either 1: 2 or 1: 1), affording the corresponding complexes [FeY2((BIP)-B-Mes)]. Relevant spectroscopic features of these compounds, such as paramagnetic H-1 NMR shifts and UV-Vis absorption bands, exhibit a marked dependence on the nature of Y. (C) 2013 Elsevier B. V.
