✦ Synopsis


Bicyclo[l.l.O]butanes upon interaction with nickel(O) catalysts undergo the intramolecular retro-carbene addition to produce reactive allylcarbene-nickel(O) intermediates, which in turn cycloadd intermolecularly, in a formal sense, across an electron-poor carbon-carbon double bond giving the cyclopropane adducts. 2 With 1,2-disubstituted olefins such as dimethyl maleate and fumarate, fairly

## 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
