Palladium- and copper-catalyzed highly selective mono-coupling between 2,6-diiodoanisoles and terminal alkynes in the production of alkynylated anisoles as potential precursors of benzo[b]furans
(Sociedade Brasileira de Química, 2014-11-01)
The coupling reaction between 2,6-diiodoanisoles and terminal alkynes using Pd(PPh3)2Cl2 and CuI as catalysts and diisopropylamine as base in toluene at room temperature for 12 h produced selectively alkynylated 2-iodoanisoles, ...
Theoretical and Experimental Study for Cross-Coupling Aldol Condensation over Mono- and Bimetallic UiO-66 Nanocatalysts
(2023)
Mono- and bimetallic UiO-66 nanocatalysts were synthesized using the solvothermal synthesis method and evaluated in the aldol condensation reaction of benzaldehyde and acetone in a batch reactor. N2 physisorption, ...
The role of thyroglobulin in thyroid hormonogenesis
(Springer, 2019-06)
In humans, the thyroid hormones T3 and T4 are synthesized in the thyroid gland in a process that crucially involves the iodoglycoprotein thyroglobulin. The overall structure of thyroglobulin is conserved in all vertebrates. ...
Raman spectroscopy of graphene: probing phonons, electrons and electron-phonon interactions.
(Universidade Federal de Minas GeraisUFMG, 2009-09-18)
Since the identification of mono and few graphene layers in a substrate in 2004, intensive work has been devoted to characterize this new material. In particular, Raman spectroscopy played an important role in unraveling ...

Glycerolysis of methyl oleate on MgO: experimental and theoretical study of the reaction selectivity
(Elsevier, 2015-01)
The liquid-phase MgO-promoted glycerolysis of methyl oleate, a fatty acid methyl ester (FAME), to give acylglycerol products was studied both, experimentally and by density functional theory (DFT). Catalytic results showed ...
Organosulphur-modified biochar: An effective green adsorbent for removing metal species in aquatic systems
(2021-02-01)
Organosulphur-modified biochar (BC) can be used as a green adsorbent for removing potentially toxic metal ions from aqueous solutions. In this study, sugarcane bagasse BCs (produced at pyrolysis temperatures from 300 to ...
