Abstract
The relative stability and the conformational behavior of symmetric multihelicene isomers of formula C66H36 are analyzed by computational means. Our efforts to synthesize some of these molecules are also reported, in particular, the observation of unexpected debromination when attempting to synthesize 13,14-dibromo[5]phenacene, and of unexpected reactivity of 13,14-dibromo[5]aphene when attempting its cyclotrimerization promoted by a nickel(0) complex.
