The metathesis of oleyl chloride (1-chloro-cis-9-octadecene) with an alkene such as 1-hexene, 5-decence, 2-butene, etc., and the disproportionation of oleyl chloride were found to be effectively catalyzed by a modified or unmodified Re2O7–Al2O3 catalyst at ambient temperature. The activity of the modified catalyst with MexOy such as V2O5, MoO3, WO3, GeO2, Re2O7–MexOy–Al2O3, was very high even at low Re contents. This reaction should be important in a synthesis of telechelic compounds or bioactive substances for insects such as sex attractant pheromones.
研究发现,改性或未改性 Re2O7-Al2O3 催化剂可在常温下有效催化油酰氯(1-氯-顺式-9-十八烯)与 1-己烯、5-癸烯、2-丁烯等烯烃的偏析反应以及油酰氯的歧化反应。含有 MexOy(如 V2O5、MoO3、WO3、GeO2、Re2O7-MexOy-Al2O3)的改性催化剂即使在 Re 含量较低的情况下也具有很高的活性。这种反应对于合成远志化合物或昆虫生物活性物质(如性引诱信息素)非常重要。
