## Abstract A one‐pot three‐component procedure to efficiently create the 1,3‐diazabicyclo[3.1.0]hex‐3‐ene system is reported. The molecular structure of 2,4,6‐triphenyl‐1,3‐diazabicyclo[3.1.0]hex‐3‐ene (**3**) was studied by X‐ray diffraction and compared to __ab initio__ and density‐functional‐th
## Abstract (1‐Diazo‐2‐oxoalkyl)silanes 1a–h react with cyclopropene 4 to form 2‐silyl‐2,3‐diazabicyclo[3.1.0]hex‐3‐enes 5 and/or 1‐silyll‐1,4‐dihydropyridazines 6. In most cases, a temperature‐ and solvent‐dependent equilibrium 5 ⇄ 6 maintained by an __N__ →__N__′ silyl shift exists in solution. W
