Despite their utility, the synthetic application of transition metal carbene complexes is often hindered by the preparation methods and stability of their carbene precursors, typically diazo compounds.3 Recent advancements have introduced methods to prepare non-stabilized carbene precursors, facilitating various reactions previously accessible through transition metal carbene complexes.4-6 References: [1] Nolan, S.P.
