[1] Synthesis of 4-methoxybiphenyl using pd-containing catalysts based on polymeric matrix of functionalized hypercrosslinked polystyrene / L. Nikoshvili, A. Bykov, A. Sidorov et al. // BULLETIN OF CHEMICAL REACTION ENGINEERING AND CATALYSIS. — 2015. — Vol. 10, no. 3. — P. 256–265. his paper describes synthesis of Pd-containing catalysts of Suzuki cross-coupling based on amino-functionalized hypercrosslinked polystyrene. The investigation of the influence of a palladium concentration, solvent composition, temperature, type and concentration of base, and a type of a gas phase was carried out. It was shown that the catalyst developed allows achieving conversion of 4-bromoanisole higher than 98% for less than 1 h at mild reaction conditions and in the absence of a phase transfer agent. Catalyst reduction was found to result in formation of small Pd nanoparticles (about 3 nm in diameter) and a large number of Pd clusters, which are highly active in Suzuki-Miyaura cross-coupling (conversion of 4-bromoanisole reached 90.2% for 3 h).
