Rhodium catalyzed reaction of internal alkynes with organoborons under CO atmosphere: a product tunable reaction
Alkynes react with organoborons under a CO atmosphere in the presence of a rhodium(I) catalyst to afford mainly 5-aryl-2(5H)-furanones, α,β-unsaturated ketones, and indanones. The product selectivity can be tuned by modifying ...
Heterogeneous Suzuki reactions catalyzed by Pd(0)-Y zeolite
The Pd(0)-Y zeolite showed high activity in the Suzuki cross-coupling reactions of aryl bromides without added ligands. The type of base and organic solvent were found to be critical for the efficiency of the reaction. The ...
Acylation of 2-methoxynaphthalene over ion-exchanged β-zeolite
Friedel-Crafts acylation of 2-Methoxynaphthalene was carried out over various ion-exchanged β zeolites (Mn+β, where Mn+: In3+, Zn2+, Al3+, Fe3+, La3+) with various anhydride (acetic, propionic and benzoic anhydrides), or ...
