Journal ArticleDOI
Palladium nanoparticles supported in a polymeric membrane: an efficient phosphine-free “green” catalyst for Suzuki–Miyaura reactions in water
Vinícius W. Faria,Deyvid G. M. Oliveira,Márcia H. S. Kurz,Fábio Ferreira Gonçalves,Carla W. Scheeren,Gilber R. Rosa +5 more
TL;DR: In this paper, Palladium(0) nanoparticles supported on a polymeric membrane, CA/Pd(0), were found to be a highly efficient "dip catalyst" for Suzuki-Miyaura cross-coupling reactions.
Journal ArticleDOI
A mixed NCP pincer palladacycle as catalyst precursor for the coupling of aryl halides with aryl boronic acids
TL;DR: The mixed pincer palladacycle (Me2NCH2(Cl)C C(CH2)2OP(i-Pr)2-κNκCκP)PdCl (3) as discussed by the authors has been shown to be a highly efficient catalyst precursor for the coupling of boronic acids and aryl chlorides.
Journal ArticleDOI
Introducing Undergraduates to Research Using a Suzuki–Miyaura Cross-Coupling Organic Chemistry Miniproject
Deyvid G. M. Oliveira,Clarissa H. Rosa,Bruna P. Vargas,Diego S. Rosa,Ma´rcia V. Silveira,Neusa Fernandes de Moura,Gilber R. Rosa +6 more
TL;DR: In this paper, a five-week miniproject is described for an upper-division experimental organic chemistry course, which includes synthesis of a phenylboronic acid via a Grignard reaction and its use in a Suzuki-Miyaura cross-coupling reaction.
Journal ArticleDOI
Batch adsorption of methylene blue dye using Enterolobium contortisiliquum as bioadsorbent: Experimental, mathematical modeling and simulation
TL;DR: In this article, the adsorption of methylene blue was studied using Enterolobium contortisiliquum as bioadsorbent, which showed structural and superficial potentiality in the process.
Journal ArticleDOI
NCP pincer palladacycle as a phosphine-free catalyst precursor for the Heck-Mizoroki coupling of aryl halides{
Gilber R. Rosa,Diego S. Rosa +1 more
TL;DR: The NCP pincer palladacycle 1 has been reported as an excellent catalyst precursor for the Suzuki-Miyaura reaction as mentioned in this paper and its properties have been evaluated in the Heck reaction.
