Hydrosilylation reactions, which allow the addition of Si-H to C=C/C≡C bonds, are typically catalyzed by homogeneous noble metal catalysts (Pt, Rh, Ir and Ru). Although excellent activity and selectivity can be obtained, the price, separation and metal residues of these precious catalysts are problems in the silicone industry. Thus, a strong interest in more sustainable catalysts and for more economic processes exists. In this respect, recently disclosed hydrosilylations using catalysts based on earth-abundant transition metals e.g. Fe, Co, Ni, and Mn and heterogeneous catalysts (supported nanoparticles and single atom sites) are noteworthy. This review describes the recent advances in this field.
