A simple and general route to aryl iodides from arenes
Abstract
Mercury(II) oxide–tetrafluoroboric acid reacts with arenes under mild or very mild conditions to afford, after treatment with iodine in a ‘one-stage’ reaction, the corresponding aryl iodide. The orientation is that expected based on general aromatic substitution theory and hence the meta-iodinated derivatives of deactivated arenes are accessible.
