摘要

采用热调节相转移钌纳米催化剂，研究了在常压氢气条件下查尔酮选择性加氢制二氢查尔酮的反应，这是该反应中首次使用的钌纳米催化剂。在最佳条件下，查尔酮转化为二氢查尔酮的转化率为98%，选择性为>99%。钌催化剂可以很容易地从产物中分离出来并循环使用三次，而转化率和选择性没有降低。该催化剂的周转频率高于已有报道的钌络合催化剂。该热调节相转移钌纳米催化剂还应用于其他α，β-不饱和酮的常压加氢反应。

A thermoregulated phase-transfer ruthenium nanocatalyst for the atmospheric hydrogenation of α,β-unsaturated ketones

The selective hydrogenation of chalcone to dihydrochalcone under atmospheric hydrogen pressure is investigated using a thermoregulated phase-transfer ruthenium nanocatalyst, representing the first ruthenium nanocatalyst used for this reaction. Under the optimal conditions, the conversion of chalcone into dihydrochalcone and the selectivity are 98% and >99%, respectively. The ruthenium catalyst can be easily separated from the product and recycled three times without any decrease in the conversion or selectivity. The turnover frequency is higher than that of a reported ruthenium complex catalyst. The thermoregulated phase-transfer ruthenium nanocatalyst is also applied for the atmospheric hydrogenation of other α,β-unsaturated ketones.

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
