Anodic oxidation in a solution containing a variety of olefins and a small amount of Mn(OAc)2.4H2O brought about Mn+3-mediated carbon-carbon bond formation, such as efficient carboxymethylation of styrene derivatives to the corresponding gamma-aryl-gamma-butyrolactones, and selective coupling of active methylene compounds with non-activated monoolefins, unconjugated dienes or 5-arylpent-1-enes.

A new, mild and practical method for conducting
manganese(III)-mediated radical reactions, which lead to the
formation of carbon–carbon bonds, has been developed using the ionic
liquid 1-butyl-3-methylimidazolium tetrafluoroborate
([bmim][BF4]).
