Ruthenium-catalyzed C-O bond activation/arylation of methoxy and O-carbamoyl-substituted fluorenones is reported. Established are new reactions of compound fluorenones. Orthogonal ruthenium-, palladium- and nickel-catalyzed reactions with Suzuki-Miyaura reactions to afford 1,4-diaryl and 1,4,8-triaryl fluorenones are also described. The ready availability of starting methoxy fluorenones by directed ortho and remote metalation tactics confers facility to the presented reactions which may find application in material science areas. DFT calculations were performed to rationalize the lack of C-H bond reactivity in the ruthenium-catalyzed reaction. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1Formula: C12H17BO3).
2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Formula: C12H17BO3
