Click-derived triazolylidenes have emerged as a powerful sub-class of NHC ligands, which offer synthetic flexibility and strong donor properties.1 We have recently exploited these ligands in combination with iron and nickel as first row transition metals,2 and discovered complexes with attractive catalytic performance in cross-coupling and specifically in reductive transformations such as hydrosilylation. Here we will introduce these complexes and discuss their catalytic potential and limitations, including mechanistic insights.
