。The metal salt to be allowed to coexist in the droesterification reaction of the present invention is a salt of at least one metal selected from the group consisting of Cu, Zn%A1, Fe, and Sb, and this includes halogen salts, sulfates, nitrates, and phosphates. In addition to inorganic acid salts such as, salts of lower carboxylic acids such as acetates may also be used. These salts may be anhydrous salts or crystalline hydrated salts. Furthermore, these may be used alone or in the form of a mixture. These metal salts have a concentration of 0.05 to 1 per palladium atom.
.. It is preferable that they coexist at an atomic ratio of 5. Atomic ratio is 0
.. If the amount added is less than 0.05, there is no effect of the addition of the metal salt. That is, there is no effect of improving the α/β ratio (i/o ratio) described above. In addition, if the atomic ratio exceeds 1.5, the metal salt itself will exhibit a different catalytic activity, and the loss due to polymerization of substituted aryl ethylene, which is a raw material, will become significant, and the catalytic ability of palladium will be suppressed. Therefore, it is undesirable.

It is a mole. The amount of the compound that can be a ligand added is 0.8 to 10 mol, preferably 1 mol per palladium atom.
~4 moles.
ヒドロエステル化反応は、反応温度は40〜200℃、
好ましくは50〜180℃で行なう。In the hydroesterification reaction, the reaction temperature is 40 to 200°C,
Preferably it is carried out at 50 to 180°C.

、実用上実施することができない。また、200℃を越
える温度では、重合等の副反応やパラジウム系カルボニ
ル化触媒の分解が生じ好ましくない。If the reaction temperature is less than 40° C., the reaction rate will be extremely slow and the reaction cannot be carried out practically. Furthermore, temperatures exceeding 200°C are undesirable because side reactions such as polymerization and decomposition of the palladium-based carbonylation catalyst occur.

のずと限界がある。従って、実用上は500 Kg/c
m2以下の圧力で充分である。The reaction pressure can be appropriately selected as long as it is 5 Kg/cm2 or more. If it is less than 5 Kg/cm2, the reaction becomes so slow that it cannot be practically carried out. Further, the higher the pressure, the more quickly the reaction proceeds, which is preferable, but too high a pressure naturally has its limits in terms of production equipment, such as the need to make the pressure resistance of the reactor extremely high. Therefore, in practice, 500 Kg/c
A pressure of less than m2 is sufficient.

Examples of solvents inert to carbonylation include polar solvents such as ethers, ketones, and alcohols, and nonpolar solvents such as paraffins, cycloparaffins, and aromatic hydrocarbons.
