ResumoBuilt-in π-alkene functionalities have been found to yield homoleptic copper(I) phenoxide and alkoxide clusters exhibiting tetrameric cubane- or hexameric ribbon-shaped structures. While tetrameric o-allylphenoxocopper(I) (1) is remarkably stable, retains its structure in solution, and resists carbonylation, hexameric methylbutenoxocopper(I) (2) dissolves in such a way that oxo-bridged copper(I) is retained, whereas π-alkene−copper(I) coordination is destroyed, leaving copper(I) free to accept carbon monoxide as a ligand.
