Abstract: A novel silica supported ferrocene appended N-heterocyclic carbene-palladium complex (SilFemBenzNHC@Pd) has been prepared and characterized by using fourier transform infrared (FT-IR), fourier transform Raman (FT-Raman), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and energy dispersive X-ray analysis (EDX). This novel complex served as a robust heterogeneous catalyst for the synthesis of biaryls via homocoupling of aryl boronic acids under base-free conditions in water. Recyclability experiments were executed successfully for six successive runs. Graphic Abstract: [Figure not available: see fulltext.]

Palladium nanoparticles supported on newly generated Al(OH)3was found to be a highly efficient catalyst in oxidative homo-couplings of (Het)aryl alkynes, (Het)arylboronic acids and potassium (Het)aryltrifluoroborates, respectively. Moderate to excellent yields of symmetrical 1,3-diynes and biaryls were obtained under mild conditions.

(Chemical Equation Presented) The Directed ortho Metalation (DoM)/Suzuki-Miyaura cross-coupling strategy is applied for the regiospecific construction of all isomeric monochloro and selected dichloro and trichloro 2,3-dihydroxybiphenyls (DHBs). The combined methodology highlights iterative DoM processes, hindered Suzuki-Miyaura couplings, and advantages in diversity in approaches from commercial starting materials leading to provision of chloro-DHBs as single isomers in high purity and on a gram scale. The syntheis of several PCBs are also reported.
