Abstract
PURPOSE: To prepare an ester useful as an intermediate of pharmaceuticals and pesticides, in high yield, without side reaction, by carboalkoxylating an organic halide having easily eliminable H at the β-position in the presence of a carbonylation catalyst containing an organic arsenic compound or an organic antimony compound.
CONSTITUTION: The organic halide of formulaI(R1WR4 are H or organic group; X is halogen) (e.g. α-phenylethyl bromide) is carboalkoxylated to the ester of formula II by the reaction with the alcohol of formula R5OH (R5 is organic group) and CO. The above reaction is carried out using a carbonylation catalyst containing an organic arsenic compound or an organic antimony compound (e.g. tetrakistriphenylarsine palladium), pref. in the presence of a basic compound such as an amine, caustic soda, etc. The side reactions such as production of olefins or ethers can be suppressed, and the reaction can be easily operated.
