Abstract
Since their discovery in 2011, gold-catalyzed transformations of vinyldiazo compounds
have become an important synthetic tool, enabling the identification of new reaction
patterns that have greatly expanded the versatility of these reagents. In this short
review, we showcase the most relevant advances that have been made in this exciting
area of research.
