Correction for ‘Cobalt-catalyzed alkyne hydrosilylation as a new frontier to selectively access silyl-hydrocarbons’ by Jung-Woo Park et al., Chem. Commun., 2022, DOI: 10.1039/d1cc06214j.

Transition-metal catalyzed stereo- and regioselective hydrosilylation of unsymmetrical alkynes

The alkyne hydrosilylation is one of the most efficient methods for the synthesis of alkenylsilicons and has been a hot topic of research for decades. This short review summarizes the progress of transition-metal-catalyzed stereo- and regioselective hydrosilylation of unsymmetrical alkynes. Topics are discussed based on different types of alkynes and the selectivities.

Synthesis and structure of thienyl Fischer carbene complexes of PtII for application in alkyne hydrosilylation

Transmetallation of group 6 thienylene Fischer carbene complexes to PtII precursors yielded new examples of neutral platinum(II) bisethoxycarbene complexes with either 2-thienyl (T) or 5-thieno[2,3-b]thienylene (TT) carbene substituents. The use...

Cobalt-Catalyzed Alkyne Hydrosilylation as a New Frontier to Selectively Access Silyl-Hydrocarbons

Hydrosilylation of alkynes is a chief chemical method in accessing a range of alkenylsilanes, which can be derivatized to obtain value-added hydrocarbons and utilized in diverse applications. While noble-metal-based catalytic...

Iridium(I) Complexes Bearing Hemilabile Coumarin-Functionalised N-Heterocyclic Carbene Ligands with Application as Alkyne Hydrosilylation Catalysts

A set of iridium(I) complexes of formula IrCl(κC,η2-IRCouR’)(cod) or IrCl(κC, η2-BzIRCouR’)(cod) (cod = 1,5-cyclooctadiene; Cou = coumarin; I = imidazolin-2-carbene; BzI = benzimidazolin-2-carbene) have beeen prepared from the corresponding azolium...

Highly Efficient and Reusable Alkyne Hydrosilylation Catalysts Based on Rhodium Complexes Ligated by Imidazolium-Substituted Phosphine

Rhodium complexes ligated by imidazolium-substituted phosphine were used as catalysts in the hydrosilylation of alkynes (1-heptyne, 1-octyne, and phenylacetylene) with 1,1,1,3,5,5,5-heptamethyltrisiloxane (HMTS) or triethylsilane (TES). In all cases, the above complexes showed higher activity and selectivity compared to their precursors ([Rh(PPh3)3Cl] and [{Rh(µ-Cl)(cod)}2]). In the reactions with aliphatic alkynes (both when HMTS and TES were used as hydrosilylating agents), β(Z) isomer was mainly formed, but, in the reaction of phenylacetylene with TES, the β(E) product was formed. The catalysts are very durable, stable in air and first and foremost insoluble in the reactants which facilitated their isolation and permitted their multiple use in subsequent catalytic runs. They make a very good alternative to the commonly used homogeneous catalysts.
