Other methods for synthesis of biaryls

Following interesting and valuable method for synthesis of polyaromatics, including well known cancerogenic structures, is the trichlorosilane-mediated palladium-catalysed homo-coupling reaction of 1,4-epoxy-1,4-dihydroarenes to biaryls [100]. For example, the reaction of 7-oxabenzonorbomadiene (536) with trichlorosilane in the 

The method is very effective in the synthesis of several naphthalene, phenanthrene, and other polyphenyl-dimers [100].
