Erami, Roghayeh Sadeghi published the artcileSuzuki-Miyaura C-C coupling reactions catalyzed by supported Pd nanoparticles for the preparation of fluorinated biphenyl derivatives, COA of Formula: C7H6BrF, the main research area is fluorobiphenyl preparation green chem; arylboronic acid aryl halide Suzuki Miyaura coupling palladium nanocatalyst.
The preparation of different fluorinated biphenyl derivatives RR1 (R = 4-fluorophenyl, 2-fluorophenyl, 3-fluorophenyl, 2-methyl-4-fluorophenyl, 2-methyl-5-fluorophenyl; R1 = Ph, 4-vinylphenyl, 4-carboxyphenyl, 4-fluorophenyl) by Suzuki-Miyaura coupling reactions catalyzed by a heterogeneous system (G-COOH-Pd-10) based on Pd nanoparticles supported onto COOH-modified graphene has been described. The catalytic activity of the hybrid material G-COOH-Pd-10 has been tested in Suzuki-Miyaura C-C coupling reactions observing excellent versatility and good conversion rates in the reactions of phenylboronic acid, 4-vinylphenylboronic acid, 4-carboxyphenylboronic acid, and 4-fluorophenylboronic acid with 1-bromo-4-fluorobenzene. In addition, the influence of the aryl bromide has been studied by carrying out reactions of 4-fluorophenylboronic acid with 1-bromo-2-fluorobenzene, 1-bromo-3-fluorobenzene, 1-bromo-4-fluorobenzene, 2-bromo-5-fluorotoluene, and 2-bromo-4-fluorotoluene. Finally, catalyst recyclability tests show a good degree of reusability of the system based on G-COOH-Pd-10 as the decrease in catalytic activity after five consecutive catalytic cycles in the reaction of 1-bromo-4-fluorobenzene with 4-florophenylboronic acid for 48 h of reaction is lower than 8%, and while in the case of reactions for three hours, the recyclability of the systems is much lower.
