Murugesan, Kathiravan published the artcileMonodisperse nickel-nanoparticles for stereo- and chemoselective hydrogenation of alkynes to alkenes, Application of Methyl 4-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethynyl)benzoate, the publication is Journal of Catalysis (2019), 372-377, database is CAplus.
The use of monosaccharides for the preparation of novel nickel nanoparticles (NP), which constitute selective hydrogenation catalysts has been reported. For example, immobilization of fructose and Ni(OAc)2 on silica and subsequent pyrolysis under inert atm. produced graphitic shells encapsulated Ni-NP with uniform size and distribution. Interestingly, fructose acts as structure controlling compound to generate specific graphitic layers and the formation of monodisperse NP. These nanoparticles enable the hydrogenation of a series of functionalized and structurally diverse aromatic, heterocyclic and aliphatic alkynes R1CCR2 (R1 = 1-hydroxyoct-8-yl, Ph, cyclohexyl, benzothiophen-3-yl, etc.; R2 = H, Et, Ph, 1,3-dioxo-1,3-dihydro-2-benzofuran-5-yl, etc.) to the corresponding alkenes R1CH=CHR2 with excellent stereo- (98-100% Z-alkene formation) and chemoselectivity.
