Oxidized Phenyl-Substituted Sesquibicyclic Hydrazines
Nelsen, Stephen F.,Wang, Yichun,Hiyashi, Randy K.,Powell, Douglas R.,Neugebauer, Franz A.
, p. 2981 - 2988 (1995)
The effect of α- and β-phenyl substituents on the neutral, +1, and +2 oxidation states of bis-N,N'-bicyclic hydrazines 1 and 2 is discussed.An α-phenyl substituent on 2 makes first electron removal 1.8 kcal/mol more difficult, but second electron removal
Probing the Dynamic Covalent Chemistry Behavior of Nitrogen-Centered Di- And Triurazole Radicals
Breton, Gary W.,Martin, Kenneth L.
, p. 10865 - 10871 (2020)
Dynamic covalent chemistry (DCvC) describes systems in which readily reversible bond formation allows for control of product distributions by straightforward manipulation of reaction conditions (e.g., changes in temperature, solvent, concentration, etc).
Silica chloride/NaNO2 as a novel heterogeneous system for the oxidation of urazoles under mild conditions
Zolfigol, Mohammad Ali,Torabi, Mehdi,Mallakpour, Shadpour E
, p. 8381 - 8384 (2001)
Urazoles and bis-urazoles can be converted in excellent yields to their corresponding triazolinediones, with a combination of silica chloride (I), wet SiO2 and sodium nitrite in dichloromethane at room temperature.
Diels-Alder Reactions of Protoporphyrin IX Dimethyl Ester
Morgan, Alan R.,Kohli, Dilmeet H.
, p. 7603 - 7606 (1995)
The reaction of a divinyl porphyrin (protoporphyrin IX dimethyl ester) with a number of azo dienophiles was studied.In all cases where reaction occurred and the product could be isolated, the expected addition product was observed.In most cases, / adducts were also identified.

, p. 1965 - 1970 (2001)
A combination of periodic or iodic acids and sodium nitrite in the presence of wet SiO2 was used as an effective oxidizing agent for the oxidation of urazoles and bis-urazoles to their corresponding triazolinediones under mild and heterogeneous conditions with good yields.

Zolfigol,Bagherzadeh,Chehardoli,Mallakpour
, p. 1149 - 1154 (2001)
A combination of potassium monopersulfate and sodium nitrite in the presence of wet SiO2 was used as an effective oxidizing agent for the oxidation of urazoles and bis-urazoles to their corresponding triazolinediones under mild and heterogeneous conditions with excellent yields.
Photolysis of matrix-isolated 4-R-1,2,4-triazoline-3,5-diones: Identification of aziridine-2,3-dione transients
Risi, Florence,Pizzala, Louis,Carles, Micheline,Verlaque, Patrick,Aycard, Jean-Pierre
, p. 666 - 670 (1996)
Matrix-isolated 4-methyl-1,2,4-triazolinedione la and 4-phenyl-1,2,4-triazolinedione 1b were photolyzed at λ335 nm and λ≥310 nm, respectively. The reactions induced by photolysis were monitored by FT-IR spectroscopy. The isocyanates 2a and 2b are always the more abundant products with carbon monoxide. Methyl- and phenylaziridine-2,3-diones (3a and 3b) were detected as minor, but well-identified reaction products. The IR experimental absorption bands were assigned by comparison with literature data and with simulated infrared spectra obtained by ab initio calculation at the 6-31G* level. Stable at the matrix temperature (10 K), 3a and 3b photolyzed to isocyanates and CO when irradiated at λ≥230 nm. Irradiation of 2b at this wavelength induces its decomposition. The kinetic data show that the rate constant process 1a→2a is faster than the 1a→3a process (3.29×10-3 and 2.35×10-4 min-1 respectively).
METHOD FOR PRODUCING SOLID TRIAZOLINEDIONE COMPOUND, SOLID TRIAZOLINEDIONE COMPOUND, AND METHOD FOR PRODUCING TRIAZOLINEDIONE COMPOUND

Paragraph 0164-0167, (2020/12/25)
Provided are a method for separating a DAPTAD-containing triazolinedione compound in solid form from a reaction solution, a separated solid triazolinedione compound, and a novel method for producing a triazolinedione compound. A triazolinedione solution in which a DAPTAD-containing triazolinedione compound is dissolved is brought into contact with a C5-15 hydrocarbon-based poor solvent to obtain a solid triazolinedione compound. Also, a triazolinedione compound is oxidized using an oxidizing agent that does not produce acid as a byproduct to obtain a triazolinedione compound.
