## Abstract Several alkynylbicyclo[1.1.0]butanes are prepared by coupling of bicyclo[1.1.0]butylmagnesium bromide with alkynyl chlorides. Severe side reactions, which take place with alkynyl bromides, are not observed. Bridgehead‐lithiated bicyclo[1.1.0]butanes are also effective components in thes
