TL;DR: The results of theoretical and experimental studies on the second-order molecular and crystal nonlinear optical susceptibilities of organic and several classes of organoelement compounds are summarised in this article.

TL;DR: In this article, a combination of X-ray structural analysis and quantum chemistry calculations was used for comparative analysis of molecular packing in the crystals of the synthesized compounds, and it was shown that the fluorinated derivative contained a shortened F···F halogen bond of the first type, and in the bromo derivative, bromine atoms formed a relatively strong Br···O=C halogen link of the second type, while the chlorine atom in the structure of chloro derivative interacted with a nitro group oxygen atom, also forming a weak Cl−·O2

TL;DR: In this paper, the first efficient trinitroethyl esterification of 2,2,2-trinitroethanol with alkanoyl, cycloalkanoyl and hetaroyl chloride was described.

TL;DR: In this paper, the reaction of 2,2-bis(methoxy-NNO-azoxy)ethanol nitrate with pyrazole, 3-nitropyrazoles, 4-nitropropyrazole or 3,4-dinitropy-razole was investigated.

TL;DR: In this paper, the reaction of acetoxyallobetulin with HClO4 in refluxing Ac2O led to a mixture of diacetoxyheterobetulonic and moronic acids, which were isolated by column chromatography in yields of 18, 37, 39, and 2%, respectively.
