摘要

报道了Amberlyst 26催化的各种脂族醛、环烷酮和苯甲醛与罗丹宁的无溶剂缩合反应。催化剂的效率、简单的后处理、简单的回收程序和高催化剂可回收性，而产率没有任何显著的几次变化，这些都是令人感兴趣的。此外，超声波辐射的急剧加速被认为是在短时间内以中等至良好产率形成亚烷基绕丹宁、环烷基绕丹宁和芳基绕丹宁的有效方法。图形摘要

Ultrasound accelerated solvent-free condensation reaction of rhodanines and carbonyls using Amberlyst 26 as a green and efficient base catalyst

The solvent-free condensation reaction of various aliphatic aldehydes, cycloalkanones, and benzaldehydes with rhodanines catalyzed by Amberlyst 26 has been reported. The catalyst's efficiency, simple work-up, simple recycling procedure, and high catalyst recyclability without any considerable change of yields several times were found to be interesting. Furthermore, the drastic acceleration of ultrasound irradiation was realized to be efficient for the formation of alkylidenerhodanine, cycloalkylidene-rhodanine, and arylidenerhodanine in moderate to good yields within a short time.

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
