Infrared spectrum of tetrafluorohydrazine was written by Durig, J. R.;Lord, R. C.. And the article was included in Spectrochimica Acta in 1963.Related Products of 5676-58-4 This article mentions the following:

The infrared spectrum of tetrafluorohydrazine was recorded and a complete vibrational analysis carried out on the assumption that the mol. belongs to the point group C₂. The 12 normal vibra tions of this point group were assigned to observed bands. The band due to the torsional vibration was observed at 122 cm.^-1 in the far infrared spectrum of the vapor. The band contours are consistent with a dihedral angle <90°. In the experiment, the researchers used many compounds, for example, 2,5-Dimethylbenzoxazole (cas: 5676-58-4Related Products of 5676-58-4).

2,5-Dimethylbenzoxazole (cas: 5676-58-4) belongs to benzoxazole derivatives. Benzoxazole derivatives have gained a lot of importance in the past few years because of their use in intermediates for the preparation of new biological materials. In the past years, numerous benzoxazole derivatives have been synthesised and evaluated for their biological potential.Related Products of 5676-58-4

Oxidative NHC Catalysis for the Generation of Imidoyl Azoliums: Synthesis of Benzoxazoles was written by Patra, Atanu;James, Anjima;Das, Tamal Kanti;Biju, Akkattu T.. And the article was included in Journal of Organic Chemistry in 2018.Name: 2-(3-Bromophenyl)benzo[d]oxazole This article mentions the following:

N-Heterocyclic carbene (NHC)-catalyzed intramol. cyclization of aldimines generated from 2-amino phenols and aromatic aldehydes leading to the synthesis of 2-arylbenzoxazoles under mild conditions is presented. The reaction proceeds via the generation of the aza-Breslow intermediates from imines and NHC, which under oxidative conditions form the key imidoyl azoliums and a subsequent intramol. cyclization furnishes the product. The reaction tolerates a broad range of functional groups, and the products are formed in generally good yields. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9Name: 2-(3-Bromophenyl)benzo[d]oxazole).

2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives.

Tri-lacunary polyoxometalates of Na₈H[PW₉O₃₄] as heterogeneous Lewis base catalysts for Knoevenagel condensation, cyanosilylation and the synthesis of benzoxazole derivatives was written by Zhao, Shen;Chen, Yang;Song, Yu-Fei. And the article was included in Applied Catalysis, A: General in 2014.Synthetic Route of C13H8BrNO This article mentions the following:

We reported for the first time the development of tri-lacunary polyoxometalates (POMs) of Na₈H[A-PW₉O₃₄]·7H₂O and Na₈H[B-PW₉O₃₄]·19H₂O (Na-A-PW₉ and Na-B-PW₉) as highly selective and efficient heterogeneous Lewis base catalysts for Knoevenagel condensation, cyanosilylation of various aldehydes and ketones and the synthesis of benzoxazole derivatives at 25° under mild conditions. Since both Na-A-PW₉ and Na-B-PW₉ display no characteristic porosity, it is proposed that the catalytic reactions proceed not only on the surface and interface, but also in the bulk phase. The catalysts can be easily recovered and reused for at least six times without obvious decrease of catalytic activities and the structures of the catalysts remain unchanged after recycling. The easy preparation, high efficiency, reusability of the heterogeneous catalysts of Na-A-PW₉ and Na-B-PW₉ exhibit great potential for further application. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9Synthetic Route of C13H8BrNO).

2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives. Although benzoxazole itself is of little practical value, many derivatives of benzoxazoles are commercially important. A number of marketed drugs are available having benzoxazole as core active moiety like, nonsteroidal anti-inflammatory drug (NSAID)—flunoxaprofen, benoxaprofen, antibiotic—calcimycin.Synthetic Route of C13H8BrNO
