Synthesis of Phenanthrenol Derivatives Through Polar Diels-Alder Reactions Employing Nitronaphthalenes and (E)-1-(Trimethylsilyloxy)-1,3- butadiene. Theoretical Calculations
(Bentham Science Publishers, 2014-02)
The cycloaddition reactions between nitronaphthalenes and 1-trimethylsilyloxy-1,3-butadiene produce phenantrenol derivatives as principal products. The primary adducts suffer the irreversible lost of nitrous acid and ...
Experimental and theoretical studies on polar Diels–Alder reactions of 1-nitronaphathalene developed in ionic liquids
(Royal Society of Chemistry, 2013)
The reactions between 1-nitronaphthalene 1 and two nucleophilic dienes, Danishefsky´s diene 2 and 1-trimethylsilyloxy-1,3-butadiene 3, to yield phenanthrenols 7 and 8 developed in protic and aprotic ionic liquids (ILs) ...
Theoretical study of the absorption and nonradiative deactivation of 1-nitronaphthalene in the low-lying singlet and triplet excited states including methanol and ethanol solvent effects
(AMER INST PHYSICSMELVILLE, 2012)
The photophysics of the 1-nitronaphthalene molecular system, after the absorption transition to the first singlet excited state, is theoretically studied for investigating the ultrafast multiplicity change to the triplet ...
Variación temporal de nitro-HAPs asociados a partículas PM2.5 en la atmosfera de las ciudades de Cuernavaca y Cuautla
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. Coordinación de Servicios de Información., 2021-12)
Debido a los daños que provocan en la salud de la población resultado de su composición las PM2.5 son un indicador muy importante de la calidad del aire en áreas urbanas. Se ha observado que algunos nitro-hidrocarburos ...
Pseudo-Pericyclic Reactions: Aromatic Compound Derivatives as Electrophiles in Polar Diels-Alder Reactions. An Experimental and Theoretical Study
(The Research Trends Editorial, 2014-11)
The Diels-Alder reaction is considered a pericyclic procces. However, depending of the structure of the diene and the dienophile the nature of this reaction can change. In the last years we have worked with aromatic nitro ...
Avaliação de adsorventes sólidos para a remoção de derivados de HPAs em solução
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-03-12)
Polycyclic aromatic hydrocarbons, nitrogen and oxygen (Nitro-PAHs and Oxy-PAHs) compose the class of compounds where a hetero atom of nitrogen and oxygen, respectively, is present in the constitution of the HPA. The inclusion ...
Determinação de compostos aromáticos nitrogenados fixos e voláteis em matrizes asfálticas empregando cromatografia líquida de alta eficiência (HPLC)
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2021-12-16)
Petroleum asphalt cement is the main source of asphalt cement today. The handling and application of the binder on the pavement is only possible with the use of high temperatures, which causes the matrix to undergo an aging ...
