Das, Anish Kumar published the artcileDefects Engineering on Ceria and C-C Coupling Reactions Using [Au11(PPh3)7I3] Nanocluster: A Combined Experimental and Theoretical Study, Recommanded Product: 4,4′-Dimethyldiphenyl, the publication is ACS Nano (2020), 14(12), 16681-16688, database is CAplus and MEDLINE.
The synthesis of Au11(PPh3)7I3 cluster that consists of an incomplete icosahedron core is reported. During its impregnation process on CeO2 support, all of the ligands were removed from the kernel and the Au11 kernel fits into the defects of ceria (embedded onto the O vacancy of ceria (111) plane). This Au11@CeO2 has high atom efficiency and catalytic activity for Ullmann-type C-C homocoupling reactions for electron rich substrates. D. functional theory calculations showed that hexagonal arrangements of Au11 kernel on (111) plane of CeO2 is the most stable one. Theor. calculations also proved that the atop Au atom has more favorable interaction with Ph iodide than the 2nd layer Au atoms of the Au11@CeO2. The present catalyst mimics the single-atom catalyst-like behavior in facilitating the coupling reactions.
