Dichloro-bis(aminophosphine) complexes of palladium with the general formula of [(P{(NC5H10)3-n(C6H11)n})2Pd(Cl)2] (where n = 0-2), belong to a new family of easy accessible, very cheap, and air stable, but highly active and universally applicable C-C cross-coupling catalysts with an excellent functional group tolerance. Dichloro{bis[1,1',1''-(phosphinetriyl)tripiperidine]}palladium [(P(NC5H10)...
Due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple and low cost method is very important. In this work, Pd nanoparticles were synthesized with narrow size distribution by loading metal salt (Pd(OAc)2 ) into the polymeric matrix (PEG) as reducing agent and stabilizer. Also, the effect of metal salt concentration and PEG molecular weight on the con...

قسمت اول: نانوذرات پالادیم قرار گرفته بر روی بسترهای فسفردار شده و بدون فسفر برای تشکیل پیوند کربن-کربن قسمت دوم: سنتز و کاربرد سنتزی نمک های آزو پیریدینیوم به عنوان مایع های یونی جدید در قسمت اول این پایان نامه، یک روش عملی و ساده برای فسفره کردن مستقیم سیلیکاژل برای تهیه سیلیکا دی فنیل فسفینیت sdpp(iv) شرح داده می شود. این سیلیکای فسفره شده با پالادیم (+2) [pd(ii)] واکنش می دهد و کاتالیزو...
Ammonia produced using renewable hydrogen is being viewed as a promising media for the export of energy from locations rich in sources. Solid oxide fuel cells (SOFCs) are efficient devices converting such exported ammonia back into electricity at point use; however, investigations on materials and operating regimes direct fuelled SOFCs limited. In this work, we evaluated SOFC performance with S...
Catalysis by palladium derivatives is now one of the most important tools in organic synthesis. Whether researchers design palladium nanoparticles (NPs) or nanoparticles occur as palladium complexes decompose, these structures can serve as central precatalysts in common carbon-carbon bond formation. Palladium NPs are also valuable alternatives to molecular catalysts because they do not require ...
