Perspective of Surfactant‐Free Colloidal Nanoparticles in Heterogeneous Catalysis

“…These processes naturally lead to a diminished active surface area and a total number of active sites per mass unit (of catalyst). While synthesis projects and publications generally aim at both; generating and sustaining active surface sites, at least a basic understanding of reaction mechanisms (e. g. structure‐activity‐ and structure‐stability‐correlations) is crucial and represents a second research topic in current and past literature on organic and inorganic reactions and applied surface science . As will be addressed throughout this manuscript, the Laser Synthesis and Processing of Colloids (LSPC) technique became a valuable method for the production of novel functional materials and model catalysts used in a broad field of research and applications .…”

Palladium nanoparticles supported on silicadiphenyl phosphinite (SDPP) as efficient catalyst for Mizoroki–Heck and Suzuki–Miyaura coupling reactions

“…In addition, they are relatively more stable and usually allow running the reaction without the exclusion of air [12]. Some industrial applications of heterogeneous catalysts have already been developed [13].…”

Reactions of nitroxides 15. Cinnamates bearing a nitroxyl moiety synthesized using a Mizoroki–Heck cross-coupling reaction

“…Cinnamic acid derivatives can be synthesized using Perkin, Knoevenagel, Claisen [ 7 ], and Wittig [ 12 ] condensation reactions. Since the discovery of catalytic coupling reactions, cinnamic derivatives have also been obtained using the Mizoroki–Heck cross-coupling reaction between aryl halides and an olefin [ 7 , 13 – 17 ]. Because cinnamates themselves are also olefins, they can serve as cinnamic substrates to synthesize more complex cinnamates [ 18 – 19 ].…”
