A Cu-catalyzed strategy was developed that harnesses a radical relay mechanism to intercept a distal C-centered radical for C-C bond formation. This approach enabled selective δ C-H (hetero)arylation of sulfonamides via intramol. hydrogen atom transfer (HAT) by an N-centered radical. The radical relay was both initiated and terminated by a Cu catalyst, which enabled incorporation of arenes and heteroarenes by cross-coupling with boronic acids. The broad scope and utility of this catalytic method for δ C-H arylation was showed, along with mechanistic probes for selectivity of the HAT mechanism. A catalytic, asym. variant was also presented, as well as a method for accessing 1,1-diaryl-pyrrolidines via iterative δ C-H functionalizations. The results came from multiple reactions, including the reaction of (3-Fluorophenyl)boronic acid(cas: 768-35-4HPLC of Formula: 768-35-4)
(3-Fluorophenyl)boronic acid(cas: 768-35-4) can be used to make novel liquid crystalline fluorobiphenylcyclohexenes and difluoroterphenyls by palladium-catalyzed cross-couplings also used in the synthesis of o-phenylphenols as potent leukotriene B4 receptor agonists.HPLC of Formula: 768-35-4
