The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.

But it is a daunting task due to emerging complexities in nanostructures and nanosynthesis. Here, we report the precision synthesis of semiconductor nanocluster via synergizing coordination, cluster, and colloidal chemistry at the nanoscale. In particular, by employing Cu26Se13(PEt2Ph)14 cluster and Cdl2(PPr3)2 coordination complex as precise precursors in colloidal cation exchange reaction, an atomically precise Cd26Se17I18(PPr3)10 cluster is produced at near- unity yield. X-ray crystallography reveals that the child CdSe cluster inherits its icosahedral-packed anion lattice and halide-phosphine-rich surface from parent cluster and complex respectively and further evolves into an enlarged structure. The hybridization of achiral precursors leads to chiral CdSe clusters co-crystallized as a 1:1 mixture of enantiomers. In-situ optical spectroscopy unveils that the reaction proceeds with well-defined pathways. Based on charge and coordination conservations, the structure of child cluster can be atomically linked to precursors via a series of transformations including surface coordination exchange, intra-cluster reorganization, and inter-cluster digestive ripening. The precision nanosynthesis with atomically defined precursors, pathways, and products is expected to further rationalize and diversify nanochemistry.
