Abstract
The rate and selectivity of hydrocarboxylation of terminal olefins in dioxane with catalysis by the PdCl/sub 2/(PPh/sub 3/)/sub 2/-PPh/sub 3/ system increases in the series C/sub 3/ < C/sub 5/ < C/sub 7/, C/sub 9/; under the mentioned conditions, the hydrocarboxylation of olefins with an internal double bond occurs significantly slower than the hydrocarboxylation of terminal olefins. The replacement of PPh/sub 3/ by SnCl/sub 2/ promotes an increase of the rate and selectivity of hydrocarboxylation of terminal olefins by PdCl/sub 2/(PPh/sub 3/)/sub 2/-SnCl/sub 2/ system and sharply retards carbonylation of olefins with an internal double bond. The side process of displacement of the double bond in 1-pentene practically does not affect the selectivity of hydrocarboxylation of this olefin in the presence of PdCl/sub 2/ x (PPh/sub 3/)/sub 2/-SnCl/sub 2/.
