alkenyldiazo compounds and unsaturated substrates. The process represents a new CC bond‐formation reaction in which alkenes, alkynes, and arenes are active reagents for the Cγ‐allylation, ‐allenylation, and ‐arylation, respectively, of alkenyldiazo substrates (see scheme). The reactivity pattern is likely to rely on the formation of a highly electrophilic alkenylgold carbenoid, which may be involved in a
