To push the system beyond 3°-alkylhalides, additional optimization (see TableS2in the Supporting Information for details) was conducted. Gratifyingly, moderate changes (aryl and alkyl iodides instead of their corresponding bromides, NiCl2·glyme replacing NiBr2and a mix solvent acetone/DMA = ...
A variety of unactivated aryl bromides, iodides and sulfonates can also undergo such a reaction smoothly. Notably, we also realize the catalytic electrochemical carboxylation of aryl (pseudo)halides with CO2 avoiding the use of sacrificial electrodes. Moreover, this sustainable and economic strategy ...
The direct reductive cross-coupling of alkyl halides with aryl halides is described. The transformation is efficient (equimolar amounts of the starting materials are used), generally high-yielding (all but one between 55 and 88% yield), highly functional-group-tolerant [OH, NHBoc, NHCbz, Bpin...
Pd–PEPPSI–IPent has proven to be an excellent catalyst for the Negishi cross-coupling reaction of secondary alkylzinc reagents with a wide variety of aryl/heteroaryl halides. Importantly, β-hydride elimination/migratory insertion of the organometallic leading to the production of isomeric coupling pr...
