Abstract
The reaction of tributylphosphine with the catalytic system (C5H5)2 TiCl2−LiC4H9 prepared in an atmosphere of H2 has been investigated in toluene solution. By using the ESR technique, a hydride complex Cp2Ti(H) (PBu3) has been detected. The proportionality between the rate of cyclohexene hydrogenation and the complex concentration has been established. The kinetics of cyclohexene hydrogenation has been investigated and a reaction mechanism is proposed.
Abstract
В толуольном растворе каталитической системы Cp2TiCl2−LiC4H9 (Cp−C5H5), приготовленной в атмосфере H2, путем комплексообразования с трибутилфосфином методом ЭПР идентифицирован гидрдный комплекс Cp2Ti(H) (PBu3). Установлена симбатная зависимость между скоростью гидрирования циклогексена и концентрацией гидрида Ti (III). Изучена кинетика гидрирования циклогексена и предложен кинетический механизм процесса.
