ylides with the structures R₃PCN₂ and R₂SCN₂ (Figure 1). These reagents enable the direct introduction of C(sp) and C(sp³)-atoms to afford alkynes, butatrienes, and even 3D structures such as (bridged) [...] ty scale. In addition to acting as potent carbon‑centered nucleophiles, mNHOs can also behave as 1,3‑dipoles and have found applications in catalysis for instance CO 2 functionalization chemistry. Furthermore [...] carbenes, resulting in novel exchange processes. Moreover, the CN₂ fragment itself can engage in 1,3‑dipolar reactions – for example, activation of white phosphorus leads to the formation of diazadiphospholes …
