Abstract: PP-134 Механизм гидрокарбоалкоксилирования олефинов при катализе комплексами Pd(II). Роль анионного лиганда The kinetics of the reaction of styrene with CO and n-butanol catalyzed by PdC12L/mL (A) and Pd(dba)/nTsOH/mL (B), where L - Ph3P, dba - dibenzylidenacetone, in dioxane (383K) was studied. The kinetic models based on the experimental results allow us to conclude that accumulation of regioisomeric products of carbonylation reaction proceeds via the three intermediate hydride complexes HPdL2-n(CO)nCl (n = 0-2) in the system A (four routes of the reaction) but only one hydride intermediate HPdL2+TsO- in the system B (two routes).
