▎ 摘  要

NOVELTY - Preparing graphene oxide supported ruthenium catalyst comprises (i) dispersing organic ligand compound and ruthenium source in a solvent, and performing reaction at 120-140 degrees C, performing solid-liquid separation and collecting the solid to obtain catalyst precursor, and (ii) dispersing the obtained catalyst precursor with graphene oxide in a medium, and reacting at 130-170 degrees C, performing solid-liquid separation and collecting solids to obtain final product. The organic ligand compound is 1-(5-(naphthalen-1-yl)thiophen-2-yl)-1H-benzo(d)(1,2,3)triazole (I). USE - The ruthenium catalyst is useful in preparing substituted ketone compounds and bisphenol F compounds (claimed). ADVANTAGE - The The ruthenium catalyst: exhibits high catalytic activity; is recyclable; can synthesizes bisphenol F under mild reaction conditions, which meets the atom economy and green chemical development idea.
