dcterms:description
Experimental effort disclosing the possibility of transition-metal mediated cross-coupling reactions on electrophilic bicyclo[1.1.1]pentane cage bridgeheads is described. It has been shown that the bridgehead-halogen bond in bicyclo[1.1.1]pentanes can undergo oxidative addition towards low-valent nickel species, yielding a new complex which reacts with organomagnesium or organolithium reagents to form a new C-C bond. Thus, the unsymmetrically substituted bicyclo[1.1.1]pentane derivatives posessing, for example, aryl funcional moieties on the bridgeheads could be prepared. Likewise, the protocol could be applied to the synthesis of [1.1.1]propellane oligomers ([n]staffanes), a class of compounds exploitable as the building blocks for supramolecular chemistry and molecular electronics Experimental effort disclosing the possibility of transition-metal mediated cross-coupling reactions on electrophilic bicyclo[1.1.1]pentane cage bridgeheads is described.
