Abstract
A series of platinum complexes featuring phosphine and isocyanide ligands [PtX<sub>2</sub>(PPh<sub>3</sub>)(CNCy)] (X = Cl, Br, and I) as well as their parent phosphine [PtX<sub>2</sub>(PPh<sub>3</sub>)<sub>2</sub>] and isocyanide [PtX<sub>2</sub>(CNCy)<sub>2</sub>] analogues have been prepared and evaluated as catalysts for the photocatalytic hydrosilylation of alkynes. Under violet light irradiation (λ<sub>max</sub> = 400 nm), phosphine-isocyanides complexes [PtX<sub>2</sub>(PPh<sub>3</sub>)(CNCy)] gave high yields of silylated products (product yield up to 99%, TONs up to 1.98 × 10<sup>3</sup>). The blue light irradiation (λ<sub>max</sub> = 450 nm) was more suitable for the parent phosphine complexes [PtX<sub>2</sub>(PPh<sub>3</sub>)<sub>2</sub>], which showed comparable efficiency (product yield up to 99%, TON up to 1.98 × 10<sup>3</sup>), while isocyanide complexes [PtX<sub>2</sub>(CNCy)<sub>2</sub>] were not active.
