Masuda, Koichiro published the artcileAerobic Dehydrogenative Coupling of Naphthols and Phenols with a Ru(OH)x/Al2O3 Catalyst under Continuous-Flow Conditions, SDS of cas: 121-00-6, the main research area is binaphthol biphenol preparation green chem continuous flow; naphthol phenol aerobic dehydrogenative coupling alumina ruthenium hydroxide catalyst.
Dehydrogenative coupling reactions of naphthols and phenols were achieved with a heterogeneous catalyst, alumina-supported ruthenium hydroxide (Ru(OH)x/Al2O3), using continuous-flow conditions and aerobic oxygen as the sole oxidant. The reactions were operated continuously for more than 16 h with good reactivity and selectivity. The Ru catalyst could be recycled at least three times by a simple online washing/activation procedure without depackaging the catalyst cartridge. The reaction provided binaphthols and biphenols as valuable products for synthetic purpose and functional materials, while an over-oxidized quinone was obtained with 2,6-Di-tert-butylphenol; combining this reaction with catalytic hydrogenation under continuous-flow conditions enabled smooth conversion of quinone to the 4,4′-biphenol derivative, which is a member of an important class of compounds for liquid crystals, engineering plastics, and other functional materials.
