The nitroaldol reaction is demonstrated as an efficient dynamic covalent reaction in phosphate buffers at neutral pH. Rapid equilibration was recorded with pyridine-based aldehydes, and dynamic oligomerization could be achieved, leading to nitroaldol dynamers of up to 17 repeating units. The dynamers were applied in a coherent stimuli-responsive molecular system in which larger dynamers transiently existed out-of-equilibrium in a neutral aqueous system rich in formaldehyde, controlled by nitromethane.
Synthesis and crystal structure of 5,5'-dinitro-[5,5'-bi-(1,3,2- dioxathiane)]2,2'-dioxide

A novel 1,3,2-dioxathiane-2-oxide derivative 5,5'-dinitro-[5,5'-bis(1,3,2- dioxathiane)]2,2'-dioxide was synthesised. Moreover, the molecular structure of the compound was confirmed by the X-ray crystal structure determination.

The condensation of nitromethane with paraformaldehyde in the presence of catalytic amounts of KF and tetra-n-butylammonium bromide in a medium of isopropanol does not afford stable 1,3-dihydroxypropanenitronic acid.In the neutralization of 2-nitro-1,3-propanediol sodium salt by anhydrous CF3COOH, 2-nitro-1,3-propanediol and 2-nitro-1-propen-3-ol were identified.
Perchlorate-free pyrotechnic formulations utilizing energetic chlorine donors: 1-CDN, 11-CDN, 13-CDN

, p. 702 - 706 (2013)
Several novel materials were investigated as energetic chlorine donors, specifically for the preparation of perchlorate-free pyrotechnic formulations with low-smoke output. The novel compounds, 2-chloromethyl-2-methyl-5,5-dinitro- 1,3-dioxane (1-CDN), 2,2-bis(chloromethyl)-5,5-dinitro-1,3-dioxane (13-CDN), and 2-(dichloromethyl)-2-methyl-5,5-dinitro-1,3-dioxane (11-CDN), were formulated with a variety of fuels and oxidizers and their resulting colored flames analyzed for color quality. The preparation and preliminary characterization of these energetic chlorine donors are described. Copyright
PROCESS FOR THE PREPARATION OF NITROALCOHOLS
-
Paragraph 0018, (2013/09/26)
A process of preparing a nitroalcohol, e.g., 2-nitro-2-methyl-1-propane, from a nitropolyol, e.g., 2-nitro-2 -methyl-1,3-propanediol, the process comprising the step of contacting under hydrogenation conditions the nitropolyol with hydrogen, a hydrogenation catalyst and, optionally, a chelating agent.
PROCESS FOR MAKING TERTIARY AMINOALCOHOL COMPOUNDS
-
Page/Page column 13, (2012/04/17)
Provided is a process for making a tertiary aminoalcohol compound. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The process uses fewer steps than conventional processes.
The Reaction of Geminal Bromonitroalkanes with Nucleophiles. Part 1. The Decomposition of 2-Bromo-2-nitropropane-1,3-diol (Bronopol) in Aqueous Base
Challis, Brian C.,Yousaf, Taher I.
, p. 283 - 286 (2007/10/02)
2-Bromo-2-nitropropane-1,3-diol decomposes in aqueous base to give tris(hydroxymethyl)nitromethane, glycolic acid, formic acid, methanol and 2,2-dinitroethanol.It also releases NO2(1-) and Br- ions but not BrO-. these products are shown to form via four concurrent decompostion pathways, three of which involve 2-bromo-2-nitroethanol as a reactive intermediate.
Addition of aldehydes to organic compounds having a carbon-hydrogen bond activated by a nitro or nitrile group
-
, (2008/06/13)
Low valent transition metal complexes containing small cone angle phosphine or arsine ligands efficiently catalyze addition of aldehydes to compounds or groups having a C--H bond activated by a nitro or nitrile group, to provide nitroalcohols or cyanohydrins, respectively.
