A Mukaiyama aldol reaction can be catalyzed by bidentate halogen bond donors with very high efficiency. The halogenated catalysts were stable over multiple consecutive runs, which supports the halogen-bond-based mode of catalysis.

Graphdiyne (GDY), an emerging two-dimensional all-carbon allotrope, features the coexistence of sp and sp2 hybridized planar carbon atoms. GDY GDY-based materials exhibit unique physical chemical properties, such as well-defined molecular skeleton, ?-conjugated structure, high specific surface area with porosity, good electrical conductivity, which have aroused widespread interest in various di...
