摘要:Fe 3 O 4 @sio 2据报道,/席夫碱/pd(II) 是一种磁性可回收的多相催化剂,用于通过催化转移氢化 (Cth) 将芳香族硝基化合物化学选择性还原为相应的胺.在这方面,将少量纳米催化剂(0.52 Mol% Pd)和水合肼添加到硝基底物中,显示出安全特性和完美的供氢能力.实验描述了芳香硝基化合物的成功还原,收率非常好,反应时间短.由于其磁性,催化剂可以简单地通过永磁体从反应混合物中分离出来,并在七个连续反应中重复使用,而不会显着降低其活性.此外,在第七次运行后,钯的浸出率仅为 3.6%.因此,图形摘要

摘要:The present invention provides a one-pot process of synthesis of phenyl naphthalene compounds that are employed as heat transfer agents. More particularly, the present invention provides a process of preparation of 1-phenylnaphthalene and 2-methyl-1-phenylnaphthalene using refinery spent catalyst. These molecules are known for application as synthetic heat transfer fluids that deliver outstanding performance and thermal stability at continuously high operating temperatures. The reaction is carried out in aqueous medium using a spent catalyst which is a palladium based charcoal catalyst as obtained from various refinery processes. Further, the present invention provides a heat resistant formulation using the synthesized polyhydrocarbons, wherein the formulation is optimized with a free radical scavenger.

标题:Process for the synthesis of protected 4-keto-proline
发明人：BETTONI PIERGIORGIO; GOBBATO STEFANO; VERONESE MARTINO; ROLETTO JACOPO; PAISSONI PAOLO

摘要:Disclosed is a process for the synthesis of N-protected 4-keto-prolines (1), starting with the corresponding protected 4-hydroxyproline, in the presence of the oxidising system P 2 O 5 /dimethylsulphoxide (DMSO). Said process can also be applied in the presence of a chiral centre in the position bearing carboxylic acid (the 3 position) without significant epimerisation of said centre. Said process is particularly advantageous from the environmental standpoint and in terms of yields, productivity and the purity of the product obtained, since it does not use chromium-based oxidants, metals such as ruthenium, or oxidising systems which are precursors of genotoxic impurities.
