“…Phototropins and flavones present in the extract were assumed to act as reducing agents for the synthesis of ArtocarpuslakoochaRoxbfor the synthesis of PdNPs 75 . This report also shows that the cellulose supported PdNPs were found to exhibit enhanced catalytic activity for the Suzuki and Heck coupling reactions in water under microwave heating.…”

Green approaches for the synthesis of nanoparticles provide advantages due to the fact that green protocols are benign and environmentally friendly. Among various green recipes, biogenic synthesis of nanoparticles have recently emerged as an active area of research due to simplicity of this method, with cost effective protocols, higher potential of reduction and low toxic effect on human health and the environment. Moreover, the biogenic reduction occurs at physiological conditions of temperature and pressure. The raw materials are easily available and therefore, the reaction can easily be scaled up. This paper presents a review to give an idea about the most reliable, cost-effective and environment friendly synthetic protocols for metal nanoparticles to control size, shape and dispersity.In this contribution, we have emphasized especially on various plants responsible for, and investigated so far, for the synthesis of palladium nanoparticles. Based on the isolated compounds/metabolites such as polyols, polyphenols, flavonoids and proteins from the respective plant extracts, a correlation is established where such metabolites are linked with the biogenic syntheses of Pd nanoparticles. Present investigation and works reviewed lead us to recommend few potential plants for the reduction of Pd 2+ ions into Pd 0 nanoparticles. This review not only summarizes the present literature but also highlights the potential of this field to open up new avenues for researchers.

A magnetically separable NiFe2O4@GO–Pd composite (GO = graphene oxide) was successfully prepared by a facile one‐pot hydrothermal strategy. This new kind of hybrid material was fully characterized using powder X‐ray diffraction, Raman spectroscopy, X‐ray photoelectron spectroscopy, transmission electron microscopy and vibrating sample magnetometry. Structural characterizations confirmed the formation of NiFe2O4 and Pd nanocrystals, and the close anchoring between nanoparticles and GO sheets. Additionally, the as‐prepared NiFe2O4@GO–Pd nanocomposite was effectively employed in the palladium‐catalyzed Heck reaction in an ethanol–water system as a green solvent. The catalyst was completely recoverable with the simple application of an external magnetic field and with no obvious loss of catalytic activity even after six repeated cycles.

“…The biogenic synthesis of cellulose supported Pd(0) nanoparticles (NPs) employing the hearth wood extract of Artocarpus lakoocha Roxb and their use as a flexible and effective catalyst in Suzuki and Heck couplings under MW heating has been reported [108]. Catalyst synthesis was followed by the observation of color changes ( Figure 4); the aqueous solution C, containing oxyresveratrol, PdCl 2 and cellulose initially displayed a light brown color and then gradually turn to black ( Figure 4D).…”

View full text Add to dashboard Cite

Eco-compatible activation methods in Suzuki-Miyaura cross-coupling reactions offer challenging opportunities for the design of clean and efficient synthetic processes. The main enabling technologies described in the literature are microwaves, ultrasound, grinding (mechanochemistry) and light. These methods can be performed in water or other green solvents with phase-transfer catalysis or even in solventless conditions. In this review, the authors will summarize the progress in this field mainly from 2010 up to the present day.
