It's complex : Ruthenium‐catalyzed [3+2] cycloaddition of ethynylcyclopropanes with aldehydes and aldimines has been found to give the corresponding 2‐ethynyltetrahydrofurans or ‐pyrrolidines in high to excellent yields. In both cases, the formation of a ruthenium allenylidene complex as a key reactive intermediate is supported by density functional theory calculations. Cp*=η 5 ‐C 5 Me 5 .
