Funktionalisierte Ethene : Dibrom(silyl)methane 2 a reagieren mit den Silylmethyl‐Grignard‐Reagentien 1 unter CoCl 2 ‐Katalyse in hervorragenden Ausbeuten zu den ( E )‐1,2‐Disilylethenen 3 a . In einer ähnlichen Transformation liefern die Dibromdisilylmethane 2 b hoch stereo‐ und regioselektiv die Trisilylethene 3 b , wenn eine stöchiometrische Menge eines Cobaltats eingesetzt wird.
