Transesterification of ethyl-10-undecenoate (derived from castor oil) with 1,4-cyclohexanedimethanol over a recyclable Cu-deposited V2O5 catalyst afforded 1,ω-diene, the corresponding cyclohexane-1,4-diylbis(methylene) bis(undec-10-enoate), a promising monomer for the synthesis of biobased polyesters, in an efficient manner. Deposition of Cu plays an important role in proceeding the reaction with high selectivity, and both the activity and the selectivity are preserved for five recycled runs by the addition of the substrates. The present catalyst was effective for transesterification with other alcohols, especially primary alcohols, demonstrating a possibility of using this catalyst for efficient conversion of plant oil to various fine chemicals.

使用 Cu 沉积 V2O5 催化剂进行 10-十一碳烯酸乙酯酯交换反应作为将植物油有效转化为单体和精细化学品的模型反应



10-十一碳烯酸乙酯(源自蓖麻油)与 1,4-环己烷二甲醇在可回收的 Cu 沉积 V 2 O 5催化剂上进行酯交换,得到 1,ω-二烯,即相应的环己烷-1,4-二基双(亚甲基)双(undec-10-enoate),一种有前途的单体,用于有效合成生物基聚酯。 Cu 的沉积在高选择性反应中发挥着重要作用,通过添加底物,在五次循环运行中都保持了活性和选择性。本催化剂对于与其他醇,尤其是伯醇的酯交换反应是有效的,证明了使用该催化剂将植物油有效转化为各种精细化学品的可能性。
