Flow reactor approach for the facile and continuous synthesis of efficient Pd@Pt core-shell nanoparticles for acceptorless dehydrogenative synthesis of pyrimidines from alcohols and amidines

Direct synthesis of triazines from alcohols and amidines using supported Pt nanoparticle catalysts via the acceptorless dehydrogenative methodology

“…The results suggest that the Pt/Al 2 O 3 catalyst is important for the dehydrogenation steps of the reaction. 36 Finally, the predicted major intermediate ( E )- N -benzylidene benzimidamide reacted with benzamidine and afforded the desired product 1,3,5-triphenyltriazine in 96% yield (eqn (5)).…”

“…We have successfully developed a new heterogeneous Pt catalyst, which is effective for the acceptorless dehydrogenative synthesis of N-heterocycles from alcohols, N-nucleophiles with base. [34][35][36] Here, we report the first example of a novel heterogeneous catalytic system (Pt/Al 2 O 3 ), for the synthesis of triazine derivatives under the acceptorless dehydrogenative coupling reactions of primary alcohols and amidines. The developed catalyst is reusable, easy separation of catalyst/product, no use of oxidants and produces green byproducts in the reaction system.…”

Gram-Scale Synthesis of CoO/C as Base for PtCo/C High-Performance Catalysts for the Oxygen Reduction Reaction

“…To solve this problem, in recent years much attention has been paid to the development of gram-scale synthesis technologies [32][33][34][35]. Such methods make it possible to produce the amount of catalysts from one to several tens of grams in a single synthesis, or to carry out a flow synthesis with continuous production of the catalyst.…”

“…In [33], platinum and nickel acetylacetonates are also used as precursors in the preparation of PtNi catalysts, and dimethyl diallyl ammonium chloride (DDAC) is used as a surfactant. In some cases, it is necessary to use complex technical devices, such as a flow reactor [34].…”
