Paragraph 0178-0181, (2019/02/04)
The invention discloses a synthetic method of an aryl alkyl thioether compound shown as formula (II), and the synthetic method is as follows: at room temperature and in a water phase, using triazene and haloalkane as reaction raw materials, using Na2S2O3 as a vulcanization reagent for reaction under the promotion effect of a copper catalyst and a Lewis acid to obtain the aryl alkyl thioether compound. The advantages of the synthetic method are as follows: reaction is efficient and yield is high; the vulcanization reagent is cheap, easy to obtain, stable, and free of irritating smell; the reaction is carried out in the solvent green water, the reaction is free of addition of a phase transfer catalyst and a volatile organic solvent, and is environmentally friendly; the reaction is carried out at room temperature, is mild in condition; the catalyst copper sulfate used in the reaction is cheap and economic reaction; the reaction substrate is easy in preparation; after amplification, the reaction efficiency is higher.

Novel heterogeneous catalyst systems based on the immobilization of Pd(0) nanoparticles onto ethylene diamine functionalized silica-cellulose substrates [Pd(0)-EDA/SCs] are reported with a view to introduce new synthetic routes under base-free conditions. The base functionalized organic/inorganic hybrid provides specific basic sites for the reactions to occur under base-free or less basic conditions, and that too with excellent yields. Moreover, the basic nitrogen sites present on the substrate can effectively stabilize and enhance the activity of Pd(0) nanoparticles by preventing their agglomeration and controlling their size. All the catalysts were characterized by TGA and FTIR analysis and the most active catalyst, [Pd(0)-EDA/SC-2] was further characterized by SEM, TEM, HRTEM, EDX, CHN and XRD studies. Additionally, it is shown that the Pd(0)-EDA/SCs exhibits excellent activity under limiting basic conditions for the C-C and C-S coupling reactions employing water as the "Green solvent". Furthermore, the novel catalyst could be recovered in a facile manner from the reaction mixture and could be reused up to five times without significant loss of catalytic activity.
