Nickel-Catalyzed Reductive Coupling of Unactivated Alkyl Bromides and Aliphatic Aldehydes [PDF]
, 2021 We report the development of a mild, convenient coupling of aliphatic aldehydes and unactivated alkyl bromides. The catalytic system features the use of a common Ni(II) precatalyst and a readily available bisoxazoline ligand and affords silyl-protected ...

Synthesis of Tetrasubstituted Allenes via Palladium-Catalyzed Cross-Coupling of Vinyl Bromides with Diazo Compounds [PDF]
, 2019 A highly efficient palladium-catalyzed cross-coupling of 2,2-diarylvinyl bromides with diazo compounds was developed, providing a convenient approach for the synthesis of tetrasubsti-tuted allenes. Both aryl diazo carbonyl compounds and N-tosylhydrazones

Pd-Catalyzed Nucleophilic Fluorination of Aryl Bromides [PDF]
, 2014 On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides ...

Copper/iron co-catalyzed alkoxycarbonylation of unactivated alkyl bromides [PDF]
, 2018 Carbonylative transformations of alkyl bromides have been explored less than those of aryl halides, in part because of the high barrier to activation of aryl bromides.
