Chemical Properties

white to off-white crystals or cryst. powder

Uses

2,3-Dimethyl-2,3-dinitrobutane (DMNB) is an additive required for commercial plastic explosives. The product has been used to develop a fast, square-wave voltammetric measurement protocol of taggant (DMNB explosive) at an unmodified carbon fiber electrode. This protocol used a phosphate buffer solution at pH 7.0.

Journal of the American Chemical Society, 96, p. 2580, 1974 DOI: 10.1021/ja00815a043The Journal of Organic Chemistry, 35, p. 295, 1970

Synthesis

The synthesis of 2,3-dimethyl-2,3-dinitrobutane is as follows:Add 4.5 g (0.05 mol) of 2-nitropropane and 9 mL of a 6 mol/L sodium hydroxide solution to a 100 mL three-necked flask. The reaction was stirred magnetically for 0.5 h in an ice-water bath, and 4 g (0.025 mol) of liquid bromine was added dropwise to the flask using a constant pressure dropping funnel. After the dropwise addition was completed, 15 mL of absolute ethanol was added to thereto, and stirring was continued in an ice bath for 0.5 h. Then the ice bath was removed, the temperature was raised to 90℃, and the reaction was refluxed for 2 hours to stop the reaction. After the reaction liquid was naturally cooled to room temperature, a large amount of white solid precipitated, filtered, washed several times with absolute ethanol and distilled water, and dried under vacuum to obtain 40.13 g of white flake crystals. The yield was 91.2%.

Check Digit Verification of cas no

The CAS Registry Mumber 3964-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3964-18:
(6*3)+(5*9)+(4*6)+(3*4)+(2*1)+(1*8)=109
109 % 10 = 9
So 3964-18-9 is a valid CAS Registry Number.

Consecutive SRN1 and ERC1 Reactions in 5-Nitroisoquinolines

Vanelle, Patrice,Rathelot, Pascal,Maldonado, Jose,Crozet, Michel P.

, p. 8385 - 8388 (1994)

The reaction of 1-(dichloromethyl)-5-nitroisoquinoline with 2-nitropropane anion which gives 1-isopropylidenemethyl-5-nitroisoquinoline as major product is shown to proceed by the consecutive SRN1 and ERC1 mechanisms.These mechanisms are confirmed by the inhibitory effects of dioxygen, p-dinitrobenzene, cupric chloride and TEMPO.

Alkali metal ion triggered conductive and stimuli-responsive metallogels

Chen, Shaorui,Li, Xiaoyuan,Yu, Xudong

, (2020/09/22)

A novel gelator NDH containing naphthalimide substituted with a 4,4,5,5-tetramethylimidazoline-1,3-diol group was synthesized and characterized. Driven by dynamic coordination interactions between the imidazoline-1,3-diol unit and alkali, NDH self-assembled into a wide range of metallogels in pentanol triggered by sonication just at room temperature. The coordination interactions between NDH and Li+ were further certified by 1H NMR and XRD analysis. The gels were characterized by several experiments such as UV–vis, fluorescent, SEM and rheology experiments. Notably, the ion conductivity of Li+/metallogels confirmed that the three dimensional network in the organogels does not affect the ions diffusion in the large interconnected liquid domains. Electrochemical impedance spectroscopy was used to prove that NDH/LiClO4-gel had stronger electrical conductivity than that of NDH/LiCl-gel.

Revisiting the Ullman's Radical Chemistry for Phthalocyanine Derivatives

Fidan, Ismail,Luneau, Dominique,Ahsen, Vefa,Hirel, Catherine

supporting information, p. 5359 - 5365 (2018/02/09)

Phthalocyanine derivatives do not cease to gain attention due to their numerous properties and applications (e.g., sensor, PDT). This makes them a unique scaffold for the design of new material. In this context, we were interested to develop the synthesis of an imino nitroxide-substituted phthalocyanine by Ullman's procedure; a challenge due to the intrinsic low solubility of most phthalocyanine derivative in much solvents. To overcome this solubility problem, we designed a phthalocyanine with bulky neopentyl substituents in peripheral positions as counterpart to the imino nitroxide moieties. The imino nitroxide-substituted phthalocyanine was obtained by condensation of a monoformyl-substituted phthalocyanine with 2,3-bis(hydroxylamino)-2,3-dimethylbutane in refluxing THF–MeOH (2:1) mixture in the presence of p-toluenesulfonic acid monohydrate, follow by oxidation with PbO2. Characterization was performed by electrochemistry, UV/Vis and EPR spectroscopy in solution as well as SQUID in solid state.
