Bicyclenproduktion: Der niedervalente Rheniumkomplex [ReCl(CO)5] katalysiert die intramolekulare Tandemcyclisierung von ω-acetylenischen Dienol-Silylethern. Das Alkin wird bei Bestrahlung in Gegenwart von 0.5–3.0 Mol-% [ReCl(CO)5] geminal C-funktionalisiert, wobei bicyclische Enol-Silylether in hoher Ausbeute gebildet werden (siehe Schema, TIPS=Triisopropylsilyl).
