Dirhodium Tetracarboxylate-promoted Reactions

Dirhodium tetracarboxylates (and related structures) are known to promote a variety of reactions, including CH-insertions and cyclopropanations. This playground has proved valuable for testing various mechanistic concepts ranging from non-statistical dynamic effects to preferential metal dissocation before catalytic cycle closure.
