However, the exploitation for selectivehydrosilylation of unsymmetrical internal alkynes has been limitedly known. Described here is a new example of this type. Specifically, [(cod)IrCl]2 catalyzes the efficient and mild hydrosilylation of thioalkynes by various silanes with excellent regio- and stereoselectivity. DFT studies suggested a new mechanism involving Ir(I) hydride as the key intermediate.

A general and mildhydrosilylation of thioalkynes is described. With the cationic catalyst [Cp*Ru(MeCN)3]+ and the bulky silane (TMSO)3SiH, a range of thioalkynes underwent smooth hydrosilylation at room temperature with excellent α regioselectivity and syn stereoselectivity. DFT calculations provided important insight into the mechanism, particularly the unusual syn selectivity with the [Cp*Ru(MeCN)3]+

An iridium‐catalyzed azide–alkynecycloaddition reaction (IrAAC) of electron‐rich internal alkynes is described. It is the first efficient intermolecular AAC of internal thioalkynes. The reaction exhibits remarkable features, such as high efficiency and regioselectivity, mild reaction conditions, easy operation, and excellent compatibility with air and a broad spectrum of organic and aqueous solvents
