## Abstract A series of di‐ and trisubstituted cyclopropyl ketones **11** were prepared by irradiation of ketones **3** and **5**, which bear a leaving group adjacent to the carbonyl C‐atom. The required ketones **3** could be easily synthesized either by functionalization of ketones **1** with a h
