A new protocol for the Ullmann-type arylation process of different aromatic heterocycles
without any transition-metal catalyst, implying the use of a combination of an excess of …

The traditional Ullmann reaction which represents the copper-catalyzed coupling between
two aryl halides to build a C–C bond was first reported in 1901. Over the time, this reaction …

Phosphine-free palladium-catalyzed Mizoroki–Heck reaction was performed using ball-
milling in polyethylene glycol under mild conditions. Good to excellent yields of coupling …

N-arylation reaction has become one of the key strategies in organic synthesis to access
several molecules of biological, agrochemical, and medicinal importance. The century-old …

Poly (ethylene glycol) s (PEGs) are an interesting environment-friendly alternative to
classical solvents. Their combination with metals and metallic salts provides powerful …

The synthesis of a novel mesoporous covalent imine polymeric (MCIPs) material, involving
