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