Pd-Catalyzed Assembly of Fluoren-9-ones by Merging of C-H Activation and Difluorocarbene Transfer

We disclose a novel Pd-catalyzed assembly of fluoren-9-ones by merging of C-H activation and difluorocarbene transfer. ClCF2COONa served as a difluorocarbene precursor to be harnessed as a carbonyl source in this transformation. The current protocol enables us to afford fluoren-9-ones in high yields with excellent functional group compatibility, which also represents the first example of using difluorocarbene as a coupling partner in transition-metal-catalyzed C-H activation.

Aza-spirobifluorene derivative and preparation method thereof

The invention discloses an aza-spirobifluorene derivative. The aza-spirobifluorene derivative is characterized by having a structural formula as shown in the specification, wherein only one of X1, X2, X3 and X4 is a nitrogen atom, and the other three are carbon atoms; and R is an aromatic or heterocyclic aromatic ring containing 6-60 carbon atoms. The aza-spirobifluorene derivative disclosed by the invention can be used as an illuminant material; the aza-spirobifluorene derivative can be independently used as an illuminating layer or doped dye for illuminating or can be formed into an exciplex with the other materials for illuminating; the aza-spirobifluorene derivative also has a carrier transporting capacity; and a group has a hole transmitting capacity and an electron transmitting capacity. The aza-spirobifluorene derivative provided by the invention can be prepared into an excellent amorphous film according to vacuum evaporation or solution methods (spin coating, printing, and the like). The aza-spirobifluorene derivative also has higher thermal stability and photo-stability.

Practical radical cyclizations with arylboronic acids and trifluoroborates

Practical radical cyclizations using organoboronic acids and trifluoroborates take place in water, open to air, and in a scalable fashion employing catalytic silver nitrate and stoichiometric potassium persulfate. Both Pschorr-type cyclizations and tandem radical cyclization/trap cascades are described, illustrating the utility of these mild conditions for the generation of polycyclic scaffolds.
