Designing and developing materials with specific properties are nowadays important tasks. These could be achieved by choosing the adequate conditions, from a myriad of possibilities, being aware that slight changes in the preparation method could have major impact on the final material. With the work presented here, we are showing that kinetically controlled surface nano-structuring (NPs formation and deposition over solid supports) in scCO2 is a versatile way for preparing active materials. Size, composition, morphol. and organization/architecture of supported metal NPs can be controlled by playing with the type of metal, metal precursor, reaction media composition (stronger or weaker reducing media) and different supports employed. Moreover, direct correlation between phys. (size, morphol., organization) and chem. properties (composition, surface chem.) are demonstrated with the systems catalytic behavior, yield and selectivity, exemplified with N-alkylation reaction of amines with alcs. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4SDS of cas: 14781-45-4).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents belong to the most important cross-coupling reaction in organic synthesis. Copper of different valence states can be used to catalyze the coupling reaction, especially the Ullmann coupling reaction. SDS of cas: 14781-45-4
