A benzene compound is prepared in a process, which comprises (i) reacting a furan compound of formula (I): wherein R1 and R2 are the same or different and independently selected from the group consisting of hydrogen, alkyl, aralkyl, -CHO, -CH2OR3, -CH(OR4 )(OR5), -COOR6, wherein R3, R4 and R5 are the same or different and are independently selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, aralkyl, alkylcarbonyl and arylcarbonyl, or wherein R4 and R5 together form an alkylene group, and wherein R6 is selected from the group consisting of hydrogen, alkyl and aryl, with an olefin of the formula (II): R7-CH=CH-R8; wherein R7 and R8 are the same or different and are independently selected from the group consisting of hydrogen, sulfonate, -CN, -CHO, and -COOR9, wherein R9 is selected from the group consisting of hydrogen, and an alkyl group, or R7 and R8 together form a –C(O)-O-(O)C- group or a –C(O)-NR10-C(O)- group, wherein R10 represents hydrogen, an aliphatic or an aromatic group, to produce an unsaturated bicyclic ether having an unsaturated carbon-carbon bond; (ii) hydrogenating the unsaturated carbon-carbon bond in the unsaturated bicyclic ether to produce a saturated bicyclic ether; and (iii) dehydrating and aromatizing the saturated bicyclic ether to produce the benzene compound.
一种苯化合物是在一个过程中制备的,该过程包括:(i)将式(I)的呋喃化合物与式(II)的烯烃反应,其中式(I)中的R1和R2分别独立选择自氢、烷基、芳基、-CHO、-CH2OR3、-CH(OR4)(OR5)、-COOR6,其中R3、R4和R5分别独立选择自氢、烷基、芳基、烷芳基、芳基烷基、烷基羰基和芳基羰基,或者R4和R5一起形成一个烷基烃基,而R6选择自氢、烷基和芳基;式(II)中的R7和R8分别独立选择自氢、磺酸酯、-CN、-CHO和-COOR9,其中R9选择自氢和烷基,或者R7和R8一起形成一个-C(O)-O-(O)C-基团或一个-C(O)-NR10-C(O)-基团,其中R10代表氢、脂肪族或芳香族基团,以生成具有不饱和碳-碳键的不饱和双环醚;(ii)氢化不饱和双环醚中的不饱和碳-碳键,以生成饱和双环醚;(iii)脱水和芳构化饱和双环醚,以生成苯化合物。
