    • PURPOSE: A process for preparing the titled compound by reacting alkyl halide compounds with aromatic compounds using a catalyst in the presence of a solvent is provided which produces alkyl aromatic compounds useful as intermediates or final products of various industrial chemicals. CONSTITUTION: An aryl aromatic compound of formula (III) is prepared by alkylating aryl halides of formula (I) and aromatic compounds of formula (II) using a catalyst selected from metal indium alone, indium and a solid base, indium and a base and a 4A molecular sieve in the presence of a solvent or in its absence. In formula, R1 and R2 denote each H or straight or side chained C1 to C5 hydrocarbon substituted to carbon of the aryl group selected from methyl, ethyl, propyl, butyl and pentyl; X denotes Cl, Br, I or F; R3 and R4 denote each H, methyl, F, hydroxyl or methyl. The aryl halides of formula (I) and aromatic compounds of formula (II) are used in a molar ratio of 100 : 1 to 1 : 100.
    • 目的:提供了一种通过在溶剂存在下使用催化剂使烷基卤化合物与芳族化合物反应制备标题化合物的方法,其产生可用作各种工业化学品的中间体或最终产物的烷基芳族化合物。 构成:通过使用选自单独的金属铟,铟和固体碱,铟和碱的催化剂烷基化式(I)的芳基卤和式(II)的芳族化合物来制备式(III)的芳基芳族化合物, 4A分子筛在溶剂存在下或在其不存在下进行。 在式中,R 1和R 2表示被取代为选自甲基,乙基,丙基,丁基和戊基的芳基的碳的每个H或直链或侧链C1至C5烃基; X表示Cl,Br,I或F; R3和R4分别表示H,甲基,F,羟基或甲基。 式(I)的芳基卤化物和式(II)的芳族化合物以100:1至1:100的摩尔比使用。
