TL;DR: In this article, the authors summarized the recent progress in the area of exoselective synthesis of polyfluorinated tricyclo[4.1.0 2.5 ]non-7-enes (tricyclononenes) and bicyclo[2.2.1]hept-5-eners (norbornenes).
Abstract: This chapter summarizes the recent progress in the area of exoselective synthesis of polyfluorinated tricyclo[4.2.1.0 2.5 ]non-7-enes (tricyclononenes) and bicyclo[2.2.1]hept-5-enes (norbornenes). The overview of the synthesis polyfluorinated exo- tricyclononenes by reactions of quadricyclane and to lesser extend, norbornadiene is given in the first part of the review. The second part contains information on stereoselective synthesis of polyfluorinated exo- norbornenes and transformations of exo- tricyclononenes.

TL;DR: Isomerization of a liquid, saturated endo-ende norbornadiene hexacyclic dimer involves the use of a catalytic amount of acidic alumina or a montmorillonite.
Abstract: Isomerization of a liquid, saturated endo-endo norbornadiene hexacyclic dimer involves the use of a catalytic amount of acidic alumina or a montmorillonite. The resulting isomeric product is solid, at ambient temperature, and can be used as a missile fuel.

TL;DR: In this paper, a series of [RuCl(dppb)(μ-Cl)3Ru(dplb)(amine)] complexes, where amine is pyrrolidine (1), piperidine (2) or perhydroazepine (3), were synthesized and characterized by elemental analysis, FTIR, UV-Vis, and 1H, 13C{1H} and 31P{ 1H} NMR spectroscopy.

TL;DR: In this article, a computational methodology for the screening of a chemical space of 1025 substituted norbornadiene molecules for promising kinetically stable molecular solar thermal (MOST) energy storage systems with high energy densities that absorb in the visible part of the solar spectrum is presented.
Abstract: We present a computational methodology for the screening of a chemical space of 1025 substituted norbornadiene molecules for promising kinetically stable molecular solar thermal (MOST) energy storage systems with high energy densities that absorb in the visible part of the solar spectrum. We use semiempirical tight-binding methods to construct a dataset of nearly 34 000 molecules and train graph convolutional networks to predict energy densities, kinetic stability, and absorption spectra and then use the models together with a genetic algorithm to search the chemical space for promising MOST energy storage systems. We identify 15 kinetically stable molecules, five of which have energy densities greater than 0.45 MJ/kg, and the main conclusion of this study is that the largest energy density that can be obtained for a single norbornadiene moiety with the substituents considered here, while maintaining a long half-life and absorption in the visible spectrum, is around 0.55 MJ/kg.

TL;DR: The photoisomerization of 7-substituted norbornadiene-cyclodextrin inclusion complexes, in which the substituents are t-butoxyl, acetoxyl and hydroxyl groups, gave the first quadricyclene inclusion complexes as mentioned in this paper.
