摘要：

The intermediate metallacycle 1 was isolated from the reaction of the corresponding (η3‐allyl)‐palladium complex with deprotonated isobutyronitrile in THF/TMEDA (TMEDA = N,N,N′,N′‐tetramethylethylenediamine). When CO was passed over a solution of 1 in dichloromethane at room temperature, the compound underwent spontaneous, stereoselective reductive elimination to form the corresponding cyclopropane.
