Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Nature Catalysis called Real-time fluorescence imaging of a heterogeneously catalysed Suzuki-Miyaura reaction, Author is Costa, Paolo; Sandrin, Deborah; Scaiano, Juan C., which mentions a compound: 625-82-1, SMILESS is CC1=CNC(C)=C1, Molecular C6H9N, Recommanded Product: 625-82-1.
The palladium-catalyzed Suzuki-Miyaura reaction is one of the most important methods for C-C cross-coupling, yet the heterogeneous version of this reaction remains poorly understood. More specifically, the question of whether the reaction occurs on the surface of the catalyst (heterogeneous process) or is promoted by leaching of palladium species in solution (homogeneous phase) is still under debate. Here, we use real-time high spatial resolution microscopy to monitor a palladium-catalyzed coupling reaction that produces a highly fluorescent BODIPY dye. We show catalyst migration during the reaction, which we attribute to a dissolution/redeposition mechanism where migrating palladium species become true active sites after attachment to the catalyst support. The observed process is heterogeneous, but the active catalysts (atoms or small clusters) have important mobility, as revealed by the observation of migrating catalytic sites. Our report shows the strength of single-mol. studies for unveiling fundamental mechanisms in heterogeneously catalyzed reactions that are otherwise difficult to explore with classical ensemble experiments [graphic not available: see fulltext]
