Abstract
Iron-nitrenoid complexes can activate C?H bonds and, thus, potentially directly transform C?H into C?N bonds. Low-coordination complexes are the main reported systems; however,octahedralironcomplexescanbeair-stablealternativesformingtheiron-nitrenoidspecies.Here,wepresentanoveloctahedralnon-hemeiron-acyl-nitrenoidcomplex.Itsreactivitywasstudiedusingaflowchemistrysetupwithonlinemassspectrometrydetection,whichallowsqualitativereactionkineticsevaluationandthedetectionoftheintermediates.Theiron-nitrenoidcomplexreactswiththiophenolbyH-Atomtransfer,followedbyareboundtoformanewN?Sbond.Thereboundintermediatecouldbedetectedanddistinguishedfromtheproductcomplex.Thereactionoftheiron-acyl-nitrenoidcomplexwithhydrocarbonsresultsintheactivationoftheC?Hbondviahydrogen-atomtransferwithnosubsequentreboundprocess
