Abstract:This review is focused on the dimerization and dissociation of aromatic C-nitroso compounds and their dimers, the reactions that could be used as a convenient model for studying the thermal organic solid-state reaction mechanisms. This molecular model is simple because it includes formation or breaking of only one covalent bond between two nitrogen atoms. The crystalline molecular solids of nitroso dimers (azodioxides) dissociate by photolysis under the cryogenic conditions, and re-dimerize by slow warming. Th… Show more

“…Formation of o-nitroso product upon release of water and methanol from 1 2 -3 2 @OA 2 was confirmed by a combination of ESI-MS, LC-DAD-MS and GC-MS S31-S35 †). Since one of the goals of this study is to sequester the toxic photo reactive nitroso release byproduct [30][31][32][33] following release of the acid, establishing the location of o-nitroso-BA and o-nitroso-BAP was critical. Locating the 1 H NMR signals of the released o-nitroso-AP from 2 and 3 was straight forward.…”

Ortho-Nitrobenzyl triggers enacapsulated within an organic capsule upon excitation release the desired acids while the unwanted used trigger ortho-nitroso product is retained within the capsule.
“…1a). [23][24][25][26][27] A relatively low energy barrier makes this reaction suitable for reversible covalent bond construction near room temperature and allows corrections of errors during polymerisation. For example, monomers with four tetrahedrally oriented nitroso groups polymerise to form crystalline 3D diamondoid azodioxy networks, which were even characterised by singlecrystal X-ray diffraction experiments.…”
CO2 adsorption properties of azo, azoxy and azodioxy-linked porous organic polymers can be predicted from the calculated electrostatic potential values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
