Abstract

in the case of phenamthrene. This may be due to the noncoplanarity in these phenanthrenes forced by the 4, 5-methyl groups. The fact that a competitive reaction in-volving the reaction of bromine with hexahelicene, a nonplanar aromatic hydrocarbon, and planar chrysene yielded mainly di-ad tetrabromohexahelicene" provides an example of interest in this connection. Although many experiments were done with a variety (12) of reagents ...
