The teaching of chemistry from the Green Chemistry perspective
(Univ. Distrital Francisco Jose de Caldas, 2016)
Green Chemistry, as a research area, understood as the development of methodologies to modify products or processes in order to reduce or eliminate the risks posed to the environment and human health. Thus it is allowing ...
Woman in chemistry. Jane Marcet, a relevant figure in chemistry education
(Soc. Brasileira Quimica, 2015)
A historiographical study of Jane Marcet's role in spreading chemistry knowledge to a wider audience in the 19th century is presented here. Her efforts to spread scientific knowledge were crucial to sharing the most important ...
Sulfur(II)-metal coordination compounds. Group VI metal carbonyl complexes with N,N′-thiobisamines ligands
(1984)
The novel complexes M(CO)5S(NR2)2 (M = Cr, Mo or W) have been prepared by the addition of N,N′-thiobisamine (NR2 = dimethylamine, piperidine, morpholine or dibenzylamine) to UV-irradiated tetrahydrofuran solutions of M(CO)6. ...
Sulphurating and coordinating properties of N,N′-thiobismorpholine towards iron carbonyls
(1990)
The reactions of N,N′-thiobismorpholine, {A figure is presented}, with Fe(CO)5, Fe2(CO)9, Fe3(CO)11 and [(η5-C5H5)Fe(CO)2THF]BF4 were examined. Thiobismorpholine undergoes desulphurization towards Fe(CO)5 with formation ...
Coriolis coupling constants of cis and trans-1,2-dichloroethylene
(1975)
Coriolis coupling constants and the inertia defect for cis- and trans-1,2-dichloroethylene have been calculated, using force constants obtained by the iterative consistency method. The results obtained are compared with ...
σ-Holes promote the concertedness in nucleophilic aromatic substitution reactions of nitroarenes
(Royal Society of Chemistry, 2019)
The mechanism of the SNAr reactions between 1-halo-2,4-dinitrobenzenes and amines was revisited by means of DFT calculations. Remarkably and contrary to the traditional text-book perspective, the dehalogenation of ...
Solvent effect on a model SNAr reaction in ionic liquid/water mixtures at different compositions
(Royal Society of Chemistry, 2018)
The reaction of phenyl 2,4,6-trinitrophenyl ether and piperidine was kinetically evaluated in BMIMBF4/water mixtures as the reaction media. This study shows the dramatic effect of the mixture composition on the reacting ...
