WebMar 4, 2024 · Direct methane aromatization (DMA) is a promising process used to convert methane to benzene, but it is limited by low conversion of methane and rapid catalyst deactivation by coking. WebAromatization is another driving force that is utilized for C–C bond activation. For example, Chaudret group reported that the C–C bond of steroid compounds can be cleaved through the Ru-promoted aromatization of the B ring. At the same time, a methane molecule is released, which is possibly another driving force for this reaction.
