    “…A novel thiophene derivative, namely 2,5-diisopropenylthiophene (DIT) was synthetized by Suzuki–Miyaura cross-coupling reaction (SMCCR). The influence of reaction parameters, such as temperature, solvent, stoichiometry of reagents, role of the base and reaction medium were thoroughly discussed in view of yield optimization and environmental impact minimization. …”

    “…Simple palladium complexes were heterogenized into red algae derived polysaccharide supports, and the effects of polysaccharide, catalyst and solvent types on the performances in a Suzuki cross-coupling reaction were tested. It was found that using palladium salts with sodium triphenylphosphine trisulfonate (TPPTS) as a ligand supported on ι-carrageenans and ethanol as the solvent yielded the best systems. …”

    “…[Image: see text] Herein we report an investigation into the synthesis, metalation, and functionalization of bis-pocket porphyrins using the Suzuki–Miyaura cross-coupling reaction. Steric limitations to accessing bis-pocket porphyrins were overcome by using this Pd-catalyzed C–C-bond-forming strategy to introduce steric bulk after macrocyclization: 2,6-dibromo-4-trimethylsilybenzaldehyde was condensed with pyrrole, and a variety of boronic acids were coupled to the resulting porphyrin in up to 95% yield. …”

    “…Herein, we describe a marine halogenating enzyme-assisted bioconjugation strategy in which an N-terminal leader peptide guides bromination of a C-terminal Trp residue in genetically encoded peptides and proteins, setting up further Trp arylation by Suzuki–Miyaura reactions. The bromination and subsequent cross-coupling reactions are residue-specific and regiospecific for the indole-6 position, occur under mild aqueous conditions, and do not require any modification of other Trp residues in the substrate peptide and/or protein. …”
