开发了一种温和的、无过渡金属的反阴离子引发的芳基化策略,该策略使用了二芳碘氟化物。开发了一种温和的、无过渡金属的反阴离子引发的芳基化策略,该策略使用了二芳碘氟化物。高价碘物种中的氟化物反阴离子表现出不同寻常的反应活性,它激活了一个酚性O-H键,导致亲电O-芳基化。在非常温和的条件下,各种酚类和二芳基碘盐都与这种转化相容。此外,我们通过证明芳基化策略与潜在的碳亲核试剂的兼容性,先发制人这一策略的更广泛的影响。
A mild and transition metal-free counteranion triggered arylation strategy has been developed using diaryliodonium fluorides. A mild and transition metal-free counteranion triggered arylation strategy has been developed using diaryliodonium fluorides. The fluoride counteranion within the hypervalent iodonium species displays unusual reactivity that activates a phenolic O–H bond leading to electrophilic O-arylation. A wide range of phenols and diaryliodonium salts are compatible with this transformation under remarkably mild conditions. Furthermore, we pre-empt the wider implications of this strategy by demonstrating the compatibility of the arylation tactic with latent carbon nucleophiles.
