Homogeneous methane activation reactions are of great interest because they offer several potential advantages over heterogeneous processes, including the stabilization of products through solvation effects, a variety of effective heat management strategies, lower reaction temperature, greater control of the reaction mechanism, and improved selectivity . The high reactivity of transition metal complexes has enabled considerable advances in homogeneous activation of methane in synthetic chemistry over the years, from the latter half of the 20th century onwards. . Although the main-group activation of inert sp 3 C -H bonds has not been nearly as well exploited as that on transition metals , it is more desirable because main group elements tend to be less toxic than late transition 2 metals. Methane activation has been reported using very strong bases in combination with a sterically hindered Lewis acid . Metal-free activation based on creating radicals has also been described . Since the introduction of frustrated Lewis pairs (FLPs) , there has been extensive effort to develop FLPs for the C -H activation by exploiting the intermolecular or intramolecular combination of unquenched Lewis centers . There has also been progress in C -H bond activation using non-FLP molecules. Driess et al.
