Despite benzyne has been known since 1940, this fascinating species has received much attention only over the last decades. The renaissance of interest in aryne chemistry is ascribable to the seminal discovery that arynes can be generated in situ from stable and commercially available precursors under mild and neutral conditions. Thanks to their high reactivity, arynes are key intermediates in countless chemical transformations ranging from cycloadditions to insertions and, among all these approaches, multicomponent reactions (MCRs) are currently standing out in this field. In particular, this short article is focused on MCRs involving the concomitant use of benzyne and isocyanides. Furthermore, the first overview on aryne MCRs triggered by α-isocyanoacetamides is presented.

Abstract
Despite benzyne has been known since 1940, this fascinating species has received much attention only over the last decades. The renaissance of interest in aryne chemistry is ascribable to the seminal discovery that arynes can be generated in situ from stable and commercially available precursors under mild and neutral conditions. Thanks to their high reactivity, arynes are key intermediates in countless chemical transformations ranging from cycloadditions to insertions and, among all these approaches, multicomponent reactions (MCRs) are currently standing out in this field. In particular, this short article is focused on MCRs involving the concomitant use of benzyne and isocyanides. Furthermore, the first overview on aryne MCRs triggered by α-isocyanoacetamides is presented.
