Perspective

Synergy between experimental and theoretical methods in the exploration of homogeneous transition metal catalysis

In this Perspective, we will focus on the use of both experimental and theoretical methods in the exploration of reaction mechanisms in homogeneous transition metal catalysis. The current state-of-the-art is highlighted using examples from the literature with particular focus on the synergy between experiment and theory.
