The synthesis, spectral characterization, and electrochemical behavior of bis(tri-n-hexylsiloxy)(2,3-phthalocyaninato)silicon left bracket SiPc(OR)//2 right bracket , its dimer left bracket RO(SiPcO)//2R right bracket , and its naphthalocyanine analog left bracket SiNc(OR)//2 right bracket are described. All compounds show near-UV absorption corresponding to Soret and N bands and intense absorption in the visible - near-IR region corresponding to Q bands. In CH//2Cl//2, within the solvent stability limit, there are two reductions and one oxidation for SiPc(OR)//2 and two reductions and two oxidations for RO(SiPcO)//2R and SiNc(OR)//2; all appear as reversible one-electron waves, although n equals 2 for the dimer. The difference in the peak potentials of the first oxidation and first reduction waves agrees well with the excitation energy and fluorescence (corresponding to Q bands) of SiPc(OR)//2 and SiNc(OR)//2.

Naphthalene and anthracene nuclei are present in several natural and synthetic compounds. Due to their unique physical and chemical properties, access to functionalized naphthalenes and anthracenes has attracted the attention of both synthetic and medicinal chemists over the decades. In this study, successive Diels–Alder/retro-Diels–Alder reactions of dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate with various bicyclic alkenes in one pot to yield naphthalene and anthracene derivatives are reported. Using anti- and syn-cyclotrimers derived from the cyclotrimerization of benzobarrelene as alkene partner enabled efficient synthesis of trinaphthylene.
Iterative synthesis of acenes via homo-elongation

supporting information; experimental part, p. 803 - 805 (2009/07/10)
Starting from aromatic ortho-dialdehydes, we devised a homo-elongation protocol that combines a Wittig olefination and subsequent intramolecular Knoevenagel condensation to produce acene diesters and dinitriles. The Royal Society of Chemistry.
