✦ Synopsis

Lithium dialkyl(l-halocyclopropyl)zincates which are generated from l,l-dibromocyclopropanes undergo intramolecular alkylation to give l-alkylcyclopropanes stereoselectively. a-Haloorganometallic compounds (so-called carbenoids) are versatile reagents which possess ambiphilic reactivity. Many useful reactions have been
