Due to its abundancy, iron provides a cheap and attractive alternative to the rare and heavy transition metals for use in catalytic transformations. 1,2,3-Triazolylidene ligand precursors are easily accessed through "click" chemistry and have proven to be versatile ligands for a range of catalytic applications.
These ligands are strong δ-donors and transform cheap, abundant iron into an efficient catalyst for hydrosilylation and semi-reduction reactions.
This work was carried out in the group of Prof. Martin Albrecht.
