Herein, we report the synthesis of tiny spherical Pd nanoparticles (NPs) by green chemical method under ambient conditions using flower extract of Lantana camara plant. The size of the Pd NPs is tunable from 4.7 to 6.3 nm by systematically controlling the concentration of either metal ions or plant extract. The synthesized Pd NPs were well characterized by different spectroscopic, microscopic and diffractometric techniques. The Pd NPs offered good size‐dependent catalytic activity in the Suzuki‐Miyaura C‐C coupling reaction under mild reaction conditions in (1: 1) water‐ethanol mixture. The catalyst is stable and exhibited excellent reusability up to three cycles of coupling reaction after which the catalytic activity decreases.

Biogenic synthesis of palladium (Pd) and platinum (Pt) nanoparticles from plants and microbes has captured the attention of many researchers because it is economical, sustainable and eco-friendly. Plant and their parts are known to have various kinds of primary and secondary metabolites which reduce the metal salts to metal nanoparticles. Shape, size and stability of Pd and Pt nanoparticles are influenced by pH, temperature, incubation time and concentrations of plant extract and that of the metal salt. Pd and Pt nanoparticles are broadly used as catalyst, as drug, drug carrier and in cancer treatment. They have shown size- and shape-dependent specific and selective therapeutic properties. In this review, we have discussed the biogenic fabrication of Pd/Pt nanoparticles, their potential application as catalyst, medicine, biosensor, medical diagnostic and pharmaceuticals.

“…In recent years, metal-catalyzed cross-coupling reactions are of strategic importance because of their applications in the production of pharmaceuticals, herbicides, natural products, intermediates, and conducting polymers. [33][34][35][36] Homogeneous palladium catalysts as traditional promoters of cross-coupling reactions suffer from some disadvantages such as high cost, difficult separation process, non-reusability, and contamination. To overcome some of these problems, palladium species were immobilized onto various support to produce heterogeneous catalysts.…”

A new heterogeneous cobalt catalyst has been synthesized by immobilizing Co species onto a nitrogen‐rich porous organic polymer (Co@imine‐POP). The heterogeneous catalyst synthesized was efficient in Heck and Sonogashira cross‐coupling reactions in green media under mild reaction conditions without inert air and phase transfer agents. This phosphine‐, copper‐, and palladium‐free catalyst was stable under the reaction conditions and could be reused for at least eight successive runs without a discernible decrease in its catalytic activity.
