RESIN HAVING RING-FUSED STRUCTUREPROBLEM TO BE SOLVED: To provide a resin which is a thermocurable or radiation-curable functional epoxy resin having high level heat resistance, electrical properties and optical properties and low shrinkage when being cured, and excellent in dispersibility and ...
Over the past century, the search for lead-free, environmentally friendly initiating substances has been a highly challenging task in the field of energetic materials. Here, an organic primary explosive featuring a fused-ring structure, 6-nitro-7-azido-p

The planarity of the ring system has been interpreted in terms of the delocalized structure (174) shown. In contrast, bismuth trichloride gave a nine-coordinate structure in which the bismuth atom was surrounded by three bicyclic ring systems. The arsenic and antimony compounds reacted with 1,1...
Fused-ring electron acceptors (FREAs) have a donor–acceptor–donor structure comprising an electron-donating fused-ring core, electron-accepting end groups, π-bridges and side chains. FREAs possess beneficial features, such as feasibility to tailor their structures, high property tunability, strong ...
For NAPTO, the nitrene intermediate formed after the N-N bond in its azide group is broken cannot undergo a transition state analogous to the six-membered ring structure observed in ICM-103. Consequently, it exists in an unstable state with a higher energy. The formation of a lower-energy,...

structure elucidation. A large number of the compounds reported in this chapter have significant biological activity and many of the intermediates presented have been patented by commercial organizations. The reactivity and synthesis sections are split in order of bicyclic ring system, starting wi...
Finally, 3E collapses to the CSS product 1F through MECP-3, forming both the cyclopropane ring and the C–Cl bond. Due to the loss of aromaticity and the strained cyclopropane structure, 1F is 29.8 kcal mol−1 higher in free energy than the starting materials 1A and B. Despite ...
