A new free-radical azocoupling has been accomplished by decomposition of diazoniumsalts with monoelectronic reducing agents in the presence of 4-methyl-3-penten-2-one. Steric and polar factors are responsible of the unusual behaviour.

transition-metal-free version of the Meerweinarylation has been developed. The key feature of this carboamination-type reaction is the slow base-controlled generation of arylradicalsfrom aryldiazonium tetrafluoroborates, so that a sufficient quantity of diazonium ions remains to enable efficient trapping of the alkyl radical adduct resulting fromarylradical addition to the alkene. Under strongly
