Ligand Free

We have demonstrated the first ligand free CuI-nanoparticle catalyzed N-arylation of amides/cyclic amides in an ethylene glycol/2-propanol solvent system under mild conditions. This is further extended for one pot synthesis of benzimidazole, and quinazolinone via intermolecular amidation followed by cyclization.

An efficient one-pot synthesis of dibenzofurans, via SNAr reaction of aryl halides and ortho-bromophenols in the presence of anhydrous K2CO3 and subsequent ligand-free palladium-catalyzed intramolecular aryl-aryl cross-coupling cyclization under microwave irradiation, is described.

A new application of carbon disulfide in the presence of KF/Al2O3is reported for the synthesis of organic symmetrical diaryl disulfides. These products were synthesized by one-pot reaction of aryl halides with thein situgenerated trithiocarbonate ion in the presence of copper under air atmosphere.

The Cross

Potassium thiocyanate acts as an efficient sulfur surrogate in C–S cross-coupling reactions mediated by recyclable copper oxide nanoparticles under ligand free conditions. This protocol avoids foul smelling thiols, for the synthesis of a variety of symmetrical diaryl sulfides, via the cross-coupling of different aryl halides with potassium thiocyanate, affording corresponding products in moderate to excellent yields.
