Zhou, Chen published the artcileA Sc(OTf)3 catalyzed dehydrogenative reaction of electron-rich (hetero)aryl nucleophiles with 9-aryl-fluoren-9-ols, Safety of 9-Phenyl-9H-xanthen-9-ol, the publication is Organic & Biomolecular Chemistry (2019), 17(44), 9615-9619, database is CAplus and MEDLINE.
A highly efficient dehydrogenative reaction of a series of (hetero)aryl nucleophiles with 9-aryl-fluoren-9-ols was realized by using only 2 mol% of Sc(OTf)3 as a catalyst. The corresponding 9,9-diarylfluorenes I [R1 = Me, Ph, 4-ClC6H4, etc.; R2 = H, Br; R3 = 1H-indol-3-yl, benzofuran-2-yl, 2-methyl-1H-indol-3-yl, etc.] were obtained in up to 99% yield. The protocol exhibited high selectivity, mild reaction conditions and good substrate compatibility. This protocol was further highlighted by its applications in the construction of potential electroluminescent materials.
Organic & Biomolecular Chemistry published new progress about 596-38-3. 596-38-3 belongs to alcohols-buliding-blocks, auxiliary class Other Aromatic Heterocyclic,Benzene,Alcohol, name is 9-Phenyl-9H-xanthen-9-ol, and the molecular formula is C10H14O, Safety of 9-Phenyl-9H-xanthen-9-ol.
