Selective Vicinal Diiodination of Polycyclic Aromatic Hydrocarbons

Vicinally diiodinated polycyclic aromatic hydrocarbons (I2-PAHs) are accessible from the corresponding diborylated B2-PAHs through boron/iodine exchange. The B2-PAHs have been prepared via twofold electrophilic borylation reactions templated by a vicinally disilylated benzene. Our protocol is applicable to fluorenes, acenes, annulated acenes, oligoaryls, and even [5]helicene. Using B2-naphthalene as the example, we have shown that the reaction scope can, in principle, be expanded to include the synthesis of vicinally dibrominated and dihydroxylated PAHs. The usefulness of the building blocks provided by our method in the field of optoelectronic materials was demonstrated by the successful conversion of I2-fluoranthene to the analogous doubly alkynylated fluoranthene emitter.

ATTEMPTS TO POLYLITHIATE TETRABROMOARENES. THE COMPATIBILITY OF METHYL SULFATE AND BUTYLLITHIUM

Tetrabromo-o- and p-dichlorobenzenes are only dilithiated, even with excess n-butyllithium, although more than two bromines are replaced by methyl groups when such solutions are treated with methyl sulfate.
