New Type

Graphdiyne (GDY) is a new type of two-dimensional (2D) carbon materials, in which two benzene rings are chained by diacetylenic linkages (-C≡C-C≡C-). γ-GDY is the most studied GDY due to its stable configuration and was experimentally obtained in 2010 through cross coupling reaction by using hexaethynylbenzene as precursor. Hydrogen substituted graphdiyne (HsGDY) was obtained using 1, 3, 5-triethynylbenzene as precursor in a similar process. Hereinto, a copper cluster doped hydrogen substituted graphdiyne nanofibers (Cu-HsGDY) were prepared through a facile one-pot in-situ synthetic approach in a good reproductive manner. Through simply removing the copper foil, the obtained robust Cu-HsGDY can be transferred onto arbitrary substrates, especially flexible substrates, such as polyethylene terephthalate (PET), which can be used as flexible electronics as future materials.

Cross Coupling Reaction

A one-pot approach towards β-methylstyrenes is reported. The transformation involves a Stille cross-coupling reaction of aryl halides with allyltributylstannane, followed by an in situ Pd-catalyzed double bond conjugative migration.

Manganese Species

Various substituted bis-(aryl)manganese species were prepared from aryl bromides by one-pot insertion of magnesium turnings in the presence of LiCl and in situ trans-metalation with MnCl2 in THF at −5 °C within 2 h. These bis-(aryl)manganese reagents undergo smooth iron-catalyzed cross-couplings using 10 mol% Fe(acac)3 with various functionalized alkenyl iodides and bromides in 1 h at 25 °C. The aryl-alkenyl cross-coupling reaction mechanism was thoroughly investigated through paramagnetic 1H-NMR, which identified the key role of tris-coordinated ate-iron(II) species in the catalytic process.

Internal Alkyne

Carbon–carbon couplings are among the most important strategies for constructing functional molecules in organic synthetic chemistry, and cheap, diverse, and readily available coupling partners are crucial to these diverse reactions. In this contribution, we report the first palladium-catalyzed C–C cross-coupling reaction of two kinds of organic halide, a gem-dibromoalkene and a halobenzene, as the starting materials. Terminal alkynes were generated in situ through a tandem elimination–hydrodebromination process, and the internal alkyne final products were synthesized in one pot. The reaction proceeded under simple, facile, and classic copper-free Sonogashira coupling reaction conditions in good to excellent yields.
