13021-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13021-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13021-02:
(7*1)+(6*3)+(5*0)+(4*2)+(3*1)+(2*0)+(1*2)=38
38 % 10 = 8
So 13021-02-8 is a valid CAS Registry Number.

Synthesis method of nitrocyclopropane

-

Paragraph 0014-0015; 0022; 0028, (2018/06/15)

The invention discloses a synthesis method of nitrocyclopropane. The synthesis method comprises the following steps: taking 1-halogenated-3-nitropropane as a raw material and taking benzyl triethyl ammonium chloride as a phase transfer catalyst under the action of sodium hydroxide to prepare the nitrocyclopropane. The method disclosed by the invention has the advantages of simplicity in operation,rapid reaction and high yield; the difficulty of rapidly and efficiently synthesizing the nitrocyclopropane is overcome; the synthesis method disclosed by the invention can be used for synthesizing an organic molecule containing a nitrocyclopropane structural unit.

Structure, Synthesis, and Properties of Some Persubstituted 1,2-Dinitroethanes. In Quest of Nitrocyclopropyl-Anion Derivatives

Kai, Yasushi,Knochel,Paul,Kwiatkowski, Stefan,Dunitz, Jack D.,Oth, Jean F. M.,et al.

, p. 137 - 161 (2007/10/02)

Attempts to deprotonate nitrocyclopropane led to solutions which showed strong ESR. signals (Fig. 1) and from which 1-nitro-1'-nitroso-bicyclopropyl (3) and 1,1'-dinitro-bicyclopropyl (2) were isolated.The activation energy for rotation about the central C,C-bond of 2 is estimated to be about 12 kcal/mol (1H-NMR. spectra in Fig. 2).In contrast, the open-chain analoque 2,3-dimethyl-2,3-dinitrobutane (1) shows a metyl singlet down to -70 deg C.Low-temperature X-ray analyses of 1, 2, 3, and also of 1,1'-dinitro-bicyclobutyl (4) show that all four molecules have gauche-conformations but reveal striking structural differences between the open-chain and the cyclic derivatives (Fig. 4-6): the central C,C-bond is long in 1 (1.575 Angstroem), short in 2 (1.479 Angstroem); the C,N-bonds are long in 1 (1.549 Angstroem), short in 2 (1.488 Angstroem); the orientation of the nitro groups is bisected in 2 and perpendicular in 1.The crystal structure of the nitro-nitroso compound 3 is isimorphous with that of the dinitro compound 2 and thus disordered (Fig. 15-16).The effect of the nitro group as ?-electron acceptor on the molecular conformations and bond lengths is discussed.From analysis of the anisotropic vibrational parameters of 2 the root-mean-square librational amplitude of the nitro groups about their C,N-bonds is estimated to be about 5.8 deg at 95 K, corresponding to a rotational barrier of about 9 kcal/mol, i. e. the same order of magnitude as the NMR. estimate of about 12 kcal/mol for C,C-rotation.
