work reports the high-yield formation of pyrazoline derivatives mediated by gold(I) catalysts. The reaction utilizes a diaziridine, which has seen only limited usage in organic methodology. Mechanisticstudies suggest a gold-mediated opening of the diazridine ring, alkyne insertion, and finally an intramolecular hydroamination to furnish the product.
