In connection with our interest in the participation of bicyclobutonium type ions in solvolytic reactions, and more specifically in the solvolysis of bicyclo[2. 1. O]pentane-5-methanol derivatives, we have examined the reactions of the exe-and endo-bicyclo[3. l.O]hexane-6-methyl tosylates (I and II)
## 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. Bridgeheadβlithiated bicyclo[1.1.0]butanes are also effective components in thes
