TL;DR: In this paper, an attempt was made to maximize the solar energy absorption in norbornadiene (1)-quadricyclane (2) system, through direct attachment of substituents at C1, C2, or C7 atoms of 1; calculating the corresponding energies at B3LYP/6-311++G** level of theory.
Abstract: An attempt is made to maximize the solar energy absorption in norbornadiene (1)-quadricyclane (2) system, through direct attachment of substituents at C1, C2, or C7 atoms of 1; calculating the corresponding energies at B3LYP/6-311++G** level of theory. The electron donating and electron withdrawing substituents of 1n-X, attached at C2, were suitable for both solar absorption bands and solar energy storage. DFT calculations indicate that the solar absorption bands of 12-X were shifted to the visible spectrum region through the electron withdrawing substituents more than through electron donating substituents.

TL;DR: In this article, it was shown by X-ray studies to contain a novel homo-Diels-Alder adduct of the diene and the acetylene, [RhCl(norbornadiene)(C4F6)]4.
Abstract: Acetylacetonato(norbornadiene)rhodium(I) reacts with 2 mol. equiv. of hexafluorobut-2-yne to give a complex in which one molecule of the acetylene links the diene to the rhodium via a rhodiacyclopentene ring; however, hexafluorobut-2-yne and chloro(norbornadiene)rhodium(I) dimer give a tetramer, [RhCl(norbornadiene)(C4F6)]4, which is shown by X-ray studies to contain a novel homo-Diels–Alder adduct of the diene and the acetylene.

TL;DR: In this article, it has been shown that metal-alcohol-liquid ammonia conditions do not reduce isolated double bonds and the "space-conjugated" norbornadiene was shown to reduce to norbonene.

TL;DR: In this paper, the synthesis of polycyclic strained molecules from norbornadiene and quadricyclane is described, which uses high pressure and involves concerted [2 + 2+2+2] or [2+ [sgrave]2+[sgrave]- processes in the first step followed by Diels-Alder cycloadditions of the primary cycloadducts 4a, 4b, 5a, 5b with cyclopen-tadiene, 1,3-cyclohexadiene.
Abstract: The synthesis of polycyclic strained molecules from norbornadiene and quadricyclane is described. The procedure uses high pressure and involves concerted [2+2+2] or [2+[sgrave]2+[sgrave]2] processes in the first step followed by Diels-Alder cycloadditions of the primary cycloadducts 4a, 4b, 5a, 5b with cyclopen-tadiene, 1,3-cyclohexadiene, furan, cycloheptatriene. The spectral NMR data of the new polycyclic molecules are given.
