Abstract

Paarbildung: Carbene mit Carbonylgruppen aktivieren weißen Phosphor sehr effektiv und liefern so carbenstabilisierte P4- und P8-Cluster. Mechanistische Belege sprechen dafür, dass der P8-Cluster (siehe Röntgenbeugungsstruktur: C grau, P gelb, N blau, O rot) das Ergebnis der [2+2]-Cycloaddition einer intermediären Diphosphenspezies ist.
