Anodic oxidation of β-ethylenic esters yields butenolides . In the presence of 1-phenyl-1-propene or α,β-disubstituted indenones a double cyclization takes place to yield more complex butenolides

Catalytically generated vinyl gold complexes from tert‐butyl allenoates were found to undergo an efficient cross‐coupling with arenediazonium salts. The gold(I)‐gold(III) redox cycle can be accessed under two different conditions, i.e., visible‐light photoredox as well as a thermally induced radical chain pathway. The current C(sp2)C(sp2) cross‐coupling protocol that is catalytic in gold, would make available
