Assembly of a multilayer film and catalytic application in Suzuki cross-coupling reaction based on synergistic effects of a conjugated organometallic pyridyl Pt(C
C)2 moiety with palladium†
Abstract
A multilayer film (Pd2+/1)n was prepared with Pd(II) ions and platinum compound trans-[Pt(PPh3)2(CCPy)2] (1) using the layer-by-layer self-assembly method. The film loaded on the quartz slide could be capable of discharging high catalytic active Pd species to promote the C–C coupling reaction, with extraordinarily low Pd-loading (6.6 × 10−6 mol%) and high catalytic efficiency in H2O–EtOH solution.
