Rings of five and six: Donor alkenyl rhodium carbenoids generated from 3,3‐dimethylcyclopropenylcarbinols exhibit high reactivity in intramolecular CH insertions. The reactions proceed under remarkably mild conditions, tolerate the presence of the free hydroxy group, and afford an efficient and stereoselective access to a variety of functionalized carbocycles and oxygen heterocycles.
