Neugebauer, Franz A. published the artcileAminyls. 7. Diarylaminyls, SDS of cas: 1821-27-8, the publication is Chemische Berichte (1974), 107(7), 2362-82, database is CAplus.

The diarylaminyls I [Rn = e.g. 4-O2N, 4-NC, 4-EtO2C, 3,5-(Me3C)2, 3,5-Me2, or 2,4,6-Me3] and II (R1 = R2 = Me or R1R2 = O) were prepared by thermal or photolytic dissociation of the corresponding hydrazines or by H abstraction from the corresponding amines and studied by ESR, as were the corresponding N-oxides. The influence of the substitution on the properties of the diphenylaminyl system and on the dissociation of the tetraarylhydrazines was discussed.

Durgaryan, A. A. published the artcileSynthesis and study of polymers containing amino, azo, and p-phenylene groups in the main chain, HPLC of Formula: 1821-27-8, the publication is Izvestiya Vysshikh Uchebnykh Zavedenii, Khimiya i Khimicheskaya Tekhnologiya (2011), 54(10), 64-69, database is CAplus.

Conducting polymers containing both, amino- and azo-groups, in the main chain exhibit unique properties of combined polyaniline and polyazoarylenes. New conducting polymers were prepared and the effect of the mol. structure and dopant (I) concentration on the elec. conductivity was investigated. Poly(azo-1,4-phenylenimino-1,4-phenylene) was obtained by the reduction of 4,4′-dinitrodiphenylamine with Zn and poly(azo-1,4-phenylenacetylimino-1,4-phenylene) was synthesized by the diazotization of 4,4′-diaminodiphenylamine and subsequent coupling with N-acetyldiphenylamine.

Liu, Hui published the artcileNanosheet-Enhanced Rhodium(III)-Catalysis in C-H Activation, Related Products of catalysis-chemistry, the publication is ACS Catalysis (2014), 4(10), 3543-3550, database is CAplus.

Rhodium(III)-catalyzed C-H activation has been promoted impressively with layered double hydroxide (LDH)-bound ligand nanosheets. A yield of >99% and a regioisomeric ratio of >20:1 have been produced in the coupling of alkenes with N-(pivaloyloxy)benzamide [e.g., N-(pivaloyloxy)benzamide + Me acrylate â†?I]. The nanosheets have been revealed to enhance the catalytic activity by affording the desired basicity and improve the regioselectivity by serving as the rigid substitution of α-amino acid ligands.

Gharagheizi, Farhad published the artcileA New Neural Network Group Contribution Method for Estimation of Upper Flash Point of Pure Chemicals, COA of Formula: C12H9N3O4, the publication is Industrial & Engineering Chemistry Research (2010), 49(24), 12685-12695, database is CAplus.

A new group contribution-based models is presented to predict the upper flash point temperature of pure compounds based on a large dataset (1294). This neural network model uses several occurrences of 122 chem. groups in a pure compound to predict its related upper flash point limit. The model squared correlation coefficient, average percent error, mean average error, and root-mean-square error over the main dataset (1294 pure compounds) were 0.99, 1.7%, 6, and 8.5, resp.
