  unactivated pyridines via multiple C(sp3/sp2)–H functionalizations of a methyl, hydroxymethyl, or aldehyde group has been developed providing a general access to all four azafluorenones. The application of this protocol is further demonstrated to the synthesis of azafluorenone related fused nitrogen heterocycles and fluorenones. In addition, design and synthesis of a novel fluorene based organic emitter for

  通过甲基，羟甲基或醛基团的多个C（sp 3 / sp 2）–H官能化作用，未活化的吡啶进行了前所未有的分子内酰化反应，从而提供了对所有四个氮杂氟烯酮的通用途径。该方案的应用进一步证明了与氮杂芴酮相关的稠合氮杂环和芴酮的合成。另外，还报道了潜在用于有机发光器件（OLED）的新型芴基有机发射体的设计和合成。

  was found to be a highly efficient monodentate transient directing group (MonoTDG) for the palladium-catalyzed direct dehydrogenative cross-coupling of benzaldehydes with arenes. A diverse set of symmetrical and unsymmetrical 9-fluorenones was readily obtained in yields of 32-72% along with excellent regioselectivities and broad functional group compatibility as well as high atom economy under mild
