Исследование развивает направление каталитического алкоксикарбонилирования арилбромидов в жидкой фазе при атмосферном давлении. В качестве каталитической системы предложена система на основе бисацетонитрилхлорида палладия, стабилизированного в промышленной полистирольной сетке MN100. В ходе исследования было изучено влияние природы фосфинового лиганда, температуры реакционной массы, а также соотношения субстрат: катализатор на скорость и интегральную селективность процесса жидкофазного алкоксикарбонилирования пара-броманизола газообразным оксидом углерода (II). Исследована активность процесса в присутствии трифенилфосфина, трифенилфосфиноксида и 4,5-бис(дифенилфосфино)-9,9-диметилксантана. The study develops the direction of catalytic alkoxycarbonylation of aryl bromides in the liquid phase at atmospheric pressure. A catalyst based on palladium bisacetonitrile chloride stabilized in an industrial MN100 polystyrene mesh is proposed as a catalytic system. In the course of the study, the influence of the nature of the phosphine ligand, the temperature of the reaction mass was studied. The effect of the substrate-to-catalyst ratio on the rate and integral selectivity of the liquid-phase alkoxycarbonylation of para-bromanisole with carbon (II) oxide gas was also studied. The activity of the process was studied in the presence of triphenylphosphine, triphenylphosphinoxide, and in the presence of 4,5-bis (diphenylphosphino)-9,9-dimethylxanthane.
