Nickel-catalyzed reductive cyclization of alkyl dihalides

The reductive coupling protocol to intramolecular cyclization of dihaloalkanes is presented. It leads to five- and six-membered rings, with the former being more efficient. The incorporation of secondary alkyl halides generally promotes coupling efficiency. To the best of our knowledge, this is the first catalytic ring-closure reaction arising from dihaloalkanes under chemical reductive conditions.

Synthesis of new chiral bis(triarylphosphine) ligands based on asymmetric hydrogenation of 4,5-diaryl-2-oxocyclopentanecarb oxylates

New chiral bis(triarylphosphine) ligands, trans-bis(3-diphenylphosphinophenyl)cyclopentane and trans-bis(2-diphenylphosphinophenyl)cyclopentane, have been prepared in optically pure forms based on asymmetric hydrogenation of 4,5-diaryl-2-oxocyclopentaneca
