This work directly compares the spectroscopic and reactivity properties of an oxoiron(IV) and an oxoiron(V) complex that are supported by the same neutral tetradentate N-based PyNMe3 ligand. A complete spectroscopic characterization of the oxoiron(IV) species (2) reveals that this compound exists as a mixture of two isomers. The reactivity of the thermodynamically more stable oxoiron(IV)

High valent iron species are very reactive molecules involved in oxidation reactions of relevance to biology and chemical synthesis. Herein we describe iron(IV)–tosylimido complexes [FeIV(NTs)(MePy2tacn)](OTf)2 (1(IV) NTs) and [FeIV(NTs)(Me2(CHPy2)tacn)](OTf)2 (2(IV) NTs), (MePy2tacn = N-methyl-N,N-bis(2-picolyl)-1,4,7-triazacyclononane, and Me2(CHPy2)tacn = 1-(di(2-pyridyl)methyl)-4,7-dimethyl-1,4,7-triazacyclononane, Ts = Tosyl). 1(IV) NTs and 2(IV) NTs are rare examples of octahedral iron(IV)–imido complexes and are isoelectronic analogues of the recently described iron(IV)–oxo
Yesterday, our former member of IQCC Oriol Planas was awarded the Premi Extraordinari for the best PhD thesis in 2018 from the University of Girona. Last year, he defended with success his PhD thesis on “Cobalt-catalyzed C-H functionalization”, supervised by Xavi Ribas and Anna Company. Now, Oriol is continuing his research as a postdoc in the group of Prof. Josep
