Dinuclear Lanthanide (III) Coordination Polymers in a Domino Reaction [PDF]

Inorganics, 2015
A systematic study was performed to further optimise the catalytic room-temperature synthesis of trans-4,5-diaminocyclopent-2-enones from 2-furaldehyde and primary or secondary amines under a non-inert atmosphere. For this purpose, a series of dinuclear lanthanide (III) coordination polymers were synthesised using a dianionic Schiff base and their ...

Copper-Promoted One-Pot Approach: Synthesis of Benzimidazoles

Molecules, 2020
A facile, one-pot, and proficient method was developed for the production of various 2-arylaminobenzimidazoles. This methodology is based for the first time on a copper catalyst promoted domino C–N cross-coupling reaction for the generation of 2 ...
