following diazotisation and loss of nitrogen is determined by the nature of the intermediates formed. Where aryl radical intermediates are formed, the selectivity parallels that found in intermolecular competition by phenyl radicals, whereas copper-catalysed decomposition of the diazonium ion leads to intermediates which seem, from their selectivity, to possess considerable cationic nature. The slower thermal

A palladium-catalyzed reaction for intermolecular selective C−H cyclocarbonylation of 2-iodobiphenyls is reported, in which the vinylenecarbonate acts as a carbon monoxide transfer agent to enable the annulation reaction.
