The hydrotalcite-supported palladium (Pd) catalyst is prepared with a green and environmentally friendly route, introducing the extract of withered leaves as a dispersant and reducing agent (Pd/LDHs-B). Compared with the as-prepared catalyst (Pd/LDHs-P with the average diameter of 4.3 nm) using a chemical synthesis method with polyvinylpyrrolidone as a dispersant and ascorbic acid (Vc) as a reductant, the results indicate that the size of Pd nanoparticles in Pd/LDHs-B is smaller (ca. 3.6 nm). The Pd-LHDs-B (0.5 mmol‰) exhibits higher activity (98.66%) than Pd/LDHs-P (98.19%) in the Suzuki reaction of 4-bromotoluene and phenylboronic acid at 60°C for 30 min. Also, the reusability of Pd/LDHs-B is confirmed by recycling tests without a significant decrease in activity.

The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
