Résumé:

Replacing noble metal-based homogeneous catalysts with base metal counterparts such as iron-based catalysts has attracted a lot of research interest. In addition to the low cost associated with the high abundance of iron, iron-based catalysts are potentially less toxic and more environmentally friendly than their noble metal counterparts. Moreover, the use of open-shell iron centers can potentially result in lower activation barriers and invoke one-electron processes that are less prevalent in noble metal chemistry. While nature uses iron-containing metalloenzymes extensively toward catalytic reactions, several applications of iron catalysis are emerging in organic synthesis as well. This lecture highlights a few recent results from our adventure with iron-based reactivity chemistry and catalysis, including alkyne dimerization,1,2 small molecule binding,3 and potential metal-alkylidene chemistry.4
