Abstract
The development of sustainable organometallic chemistry is one of the many challenges that chemists must address to solve environmental issues. Until now, the classical approach was to develop highly selective homogeneous catalysts for a single transformation. However, a new area of research focuses on the execution of two or more reactions in the same vessel using heterogeneous multitask catalysts. This approach results in a reduced number of operations leading to time and cost benefits. Moreover, owing to the scarcity of natural resources and the recent dramatic cost increase of these resources and metals, the development of recyclable heterogeneous catalysts is urgent. This Minireview focuses on the latest developments in tandem reactions promoted by heterogeneous multitask catalysts.
