Tandem reactivity of a redox-active Frustrated Lewis Pair for H2 oxidation on [FeFe]-platform – OxySplit-H2

Submission summary

Development of efficient, eco- and environment friendly substrates for the oxidation of H2, a green energy carrier, is required to substitute rare and expensive noble metals. Frustrated Lewis Pairs (FLP) allow the heterolysis splitting of H2 but no electron is released from H2. Inspired by [FeFe]-hydrogenases in nature, organometallic models are developed, but very few are able to oxidise H2. Aiming H2 oxidation, this project propose to study the intermolecular or intramolecular FLP formed by a borane-based Lewis acid associated to a cooperative bimetallic assembly Fe(I)Fe(I) acting as a Lewis base, able to transfer both electrons and protons. Novel FLP combining a [FeFe] bimetallic complex and a borane will be characterized by spectroscopic and electrochemical methods, reactivity with H2 will then be studied.
