3-dibromoadamantanes carrying alkyl, phenyl, and alkoxy substituents were converted into the corresponding DHAs via the intramolecular Wurtz-type coupling reactions with lithium metal in THF in 21–81% yields. A series of highly strained [3.3.1]propellane derivatives, 1,3-dehydroadamantanes (DHAs) possessing alkyl, phenyl, and alkoxy substituents, such as 5-butyl, 5-hexyl, 5-octyl, 5-phenyl, 5-methoxy, 5-butoxy
