The functionalization of aryl and heteroaryls using α‐carbonylsulfoxoniumylides without the help of a directing group has remained so far a neglected area, despite the advantageous safety profile of sulfoxoniumylides. Described herein are the cyclizations of α‐carbonylsulfoxoniumylides onto benzenes, benzofurans and N‐p‐toluenesulfonyl indoles in the presence of a base in HFIP, whereas pyrroles
