Project description
A route to efficient and sustainable methane functionalisation
Methane, the main ingredient found in natural gas, is used chiefly as a burning fuel; alternatively, it can be converted into a useful mixture called synthesis gas. Despite advances in the field, methane’s versatile use is hindered by its low intrinsic reactivity. The principal strategy the EU-funded BECAME project will follow to increase methane's reactivity is to use one transition metal complex to activate the carbon-hydrogen bonds, and another transition metal complex to catalyse the methylation process. BECAME researchers expect the proposed method to reveal more about catalytic cross-coupling reactions and carbon-hydrogen activation, and serve as a fundamental basis for efficient and sustainable methane functionalisation.
Objective
One of the remaining primary challenges in modern chemistry is the development of clean, energy- and cost-efficient catalytic processes that can allow to convert simple and abundant chemical feedstocks into high value-added products. Given the vast reserves of methane from natural gas, available worldwide, the direct use of the simplest alkane as source of fuels and chemicals could have a great impact in our society. However, methanes low intrinsic reactivity has rendered its use extremely difficult for purposes beyond aerobic combustion and the production of syngas. Despite some recent advances in the field, a general strategy for a diverse and versatile use of methane is elusive.
The overall aim of this proposal is the development of a new paradigm in catalysis which can provide new catalytic processes that allow direct methane functionalization by using it as a methylating reagent in a variety of C-C bond forming reactions.
The approach described in this proposal is based on a cooperative interaction between two transition metal complexes in which an early transition metal is responsible for the methane C-H activation and a late transition metal is the actual catalyst of the methylation process. The link between these two processes is a transmetalation step and will be used to transfer the mechanism of typical cross-coupling reactions to the field of methane functionalization.
New pathways for the direct use of methane in reactions such as allylic alkylation, conjugate addition, cross-coupling, C-H methylation and alkene hydromethylation will be developed based on this novel bimetallic catalytic strategy.
It is envisioned that the proposed research will lead to a new concept at the interface of catalytic cross coupling reactions and C-H activation. It will contribute to the fundamental understanding of these two reactions and will provide the basis for a new technology for energy efficient and environmentally friendly, thus sustainable, methane conversion.
