Abstract: Die Metall-Ligand-Kooperation (MLC) hat sich zu einem wichtigen Konzept in der Ubergangsmetallkatalyse in synthetischen und biologischen Systemen entwickelt. MLC bedeutet, dass sowohl das Metall als auch der Ligand direkt an der Bindungsaktivierung beteiligt sind, im Gegensatz zur klassischen Ubergangsmetallkatalyse, wo der Ligand (z. B. Phosphan) nur als “Zuschauer” agiert und samtliche Schlusseltransformationen am Metallzentrum ablaufen. In diesem Aufsatz diskutieren wir Beispiele von Metall-Ligand-Kooperationen, bei denen 1) sowohl das Metall als auch der Ligand im Verlauf der Bindungsaktivierung chemisch modifiziert werden und 2) die Bindungsaktivierung zu unmittelbaren Anderungen in der ersten Koordinationsschale fuhrt, selbst wenn das reaktive Zentrum im Liganden nicht direkt an das Metall bindet. Die Bedeutung der Metall-Ligand-Kooperation fur effiziente Katalyseprozesse, aber auch fur die Katalysatordeaktivierung, wird besprochen.
