Bidirectional Synthesis, Photophysical and Electrochemical Characterization of Polycyclic Quinones Using Benzocyclobutenes and Benzodicyclobutenes as Precursors

Quinones have widespread applications in view of their interesting chemical and photophysical features. On the other hand, benzocyclobutenes (BCBs) are generally masked reactive dienes suitable for the [4+2] cycloaddition reactions. Here, benzocyclobutenes and benzodicyclobutenes (BDCBs) were prepared and further reacted with benzoquinone and naphthoquinone in order to obtain some new polycyclic quinones with highly extended π systems, namely, 6-bromo-5,8-dimethoxyanthracene-1,4-dione, 2,9-dibromo-1,4,8,11-tetramethoxypentacene-6,13-dione, 9-bromo-7,10-dimethoxytetracene-5,12-dione, 3,10-dimethoxycyclobuta[b]anthracene-1,5,8(2H)-trione, 6,10,17,21-tetramethoxynonacene-1,4,8,12,15,19-hexaone, and 3,12-dimethoxycyclobuta[b]tetracene-1,5,10(2H)-trione. In addition to their spectroscopic characterization the new compounds are investigated by UV and fluorescence spectroscopy, cyclic voltammetry, and DFT calculations.

Allylic vs. Vinylic Deprotonation Reactions of Cyclic Vinyl Ethers. 7-Lithio-2,3,4,5-tetrahydrooxepin: Synthesis and Carbon-13 Nuclear Magnetic Resonance Spectrum

2,3,4,5-Tetrahydrooxepin treated with either n-butyllithium or tert-butyllithium affords 7-lithio-2,3,4,5-tetrahydrooxepin.The question of allylic vs. vinylic deprotonation of cyclic vinyl ethers was examined by varying ring size and degree of unsaturation.Carbon-13 spectral data for the anions obtained from 2,5-dihydrofuran, 2,3-dihydrooxepin, and 2,3,4,5-tetrahydrooxepin are reported.In contrast to 2,3,4,5-tetrahydrooxepin, 2,3-dihydrooxepin undergoes allylic deprotonation, possibly as a result of a slightly larger C-C=C bond angle in the dihydrooxepin as compared to that of the tetrahydrooxepin.
