Water Soluble Starch Stabilized Palladium Nanoparticle: Efficient Catalyst for Miyaura‐Suzuki Coupling Reaction

Abstract

The fabricated water soluble starch stabilized palladium nanoparticle promoted Miyaura-Suzuki coupling reaction with high catalytic activity and selectivity and in excellent yields, which include recovery and re-use of this catalyst at least three times.

The use of polysaccharides and derivatives in palladium-catalyzed coupling reactions

“…A wide range of educts was also tested by using palladium particles stabilized by water-soluble starch. 21 The catalyst was prepared by reducing Na 2 [PdCl 4 ] with sodium ascorbate in a starch solution. High yields were reported for the iodo-and bromobenzenes (Scheme 3).…”

Microwave assisted cross-coupling reactions using palladium nanoparticles in aqueous media

“…described the catalytic ability of starch based palladium nanoparticle (PdNP) to catalyze Suzuki-Miyaura coupling. [15] In their report, the particle size increased over successive recycling of the catalyst and the activity went down to 20% after 6 th cycle. The decrease in yield was possibly due to the agglomeration of the nanoparticles.…”

Suporte Lignocelulósico De Bambu Impregnado Com Paládio E Sua Aplicação Para Reação De Suzuki

“…Estas puderam ser reutilizadas 3 vezes sem grandes perdas de rendimento. 81 Metodologias para realizar a reação de Suzuki em microrreatores também foram desenvolvidas. Esses sistemas apresentam vantagens como segurança, otimização no uso da energia, redução do volume de solvente necessário e da geração de resíduos, fácil ampliação da escala de produção, pouco espaço para instalação, manuseio e manutenção e a possibilidade de implementação de técnicas analíticas para controle de processos, que os tornam vantajosos tanto para aplicações em laboratórios de pesquisa quanto em processos industriais.…”
