Ultrasound assisted synthesis of 1,5-disubstituted pyrazole using Cu(I) catalyst

A new efficient and convenient approach towards the synthesis of pyrazole is described. The α,β-unsaturated cyanoesters were obtained from substituted benzaldehyde and ethyl cyanoacetate by reported methods. 1,5-Disubstituted pyrazoles were synthesized fr

PROCESS FOR PREPARING A PROPIOLIC ACID OR A DERIVATIVE THEREOF

The invention relates to a process for preparing a propiolic acid or a derivative thereof by reacting a terminal alkyne with carbon dioxide, which comprises performing the reaction in the presence of a base and a copper complex, especially a copper (I) complex having at least one ligand, at least one of the ligands of the copper complex being selected from monodentate ligands which have an aminic or iminic nitrogen atom capable of coordination with copper, and polydentate ligands having at least two atoms or atom groups which are capable of simultaneous coordination with copper and are selected from nitrogen, oxygen, sulfur, phosphorus and carbene carbon.

Methods of 1,3-enyne preparation using copper (I) catalysts

A copper(I) bi-dentate ligand complex-catalyzed procedure for synthesis of 1,3-enynes. The methods and/or systems of this invention afford a variety of enynes, tolerate a variety of sensitive functional groups, and can be employed without resort to expensive palladium reagents.

Methods and systems for preparing fused heterocyclic compounds using copper(I) catalysts

A copper(I)-catalyzed procedure for the synthesis of benzo[b]heterocycles. This protocol can be used to synthesize a variety of 2-arylbenzo[b]furans and indoles in good to excellent yields. This method can tolerate a variety of functional groups, does not require the use of expensive additives and is palladium-free.
