    Abstract: PROBLEM TO BE SOLVED: To provide a synthetic organic catalyst which shows high catalytic activity under a relatively mild condition, and can be easily separated from products after reaction to be reused, and its simple manufacturing method. SOLUTION: A sub-nano order palladium catalyst immobilized between montmorillonite layers is made by immobilizing sub-nano order palladium clusters between montmorillonite crystal layers. The sub-nano order palladium catalyst can be manufactured by the manufacturing method comprising a process for obtaining palladium (II) type montmorillonite by treating alkaline earth metal type montmorillonite with a divalent palladium complex, and a process for treating the obtained palladium (II) type montmorillonite with a reducing agent.

    Abstract: PURPOSE:To readily obtain a halogenated substance in high yield by treating an aromatic compound with a benzyltri-lower alkyulammonium trihalide in the presence of a Lewis acid. CONSTITUTION:An aromatic compound is treated with a compound expressed by the formula (R1 to R3 are 1-6C alkyl) X is halogen) in the presence of a Lewis acid (e.g., zinc chloride or bromide) to afford a halogenated substance. AlCl3 and AlBr3 in the Lewis acid are not preferred, since both will decompose the compound expressed by the formula. Furthermore, in order to enhance reactivity, the treatment may be carried out in the coexistence of an alkaline (earth) metal carbonate or hydrogencarbonate, etc., for the purpose of trapping hydrogen halides formed as a by-product. A solvent capable of dissolving the compound expressed by the formula may be used and acetic acid, dichloromethane, etc., are cited. Even the aromatic compound having low reactivity can be readily halogenated according to the above-mentioned method.
