Short communicationFunctionalised [(NHC)Pd(allyl)Cl] complexes: Synthesis, immobilisation and application in cross-coupling and dehalogenation reactions

- A novel [(NHC)PdII] unit has been immobilised on silica coated nanoparticles.
- Good activity shown in Suzuki-Miyaura and chloroarene dehalogenation reactions.
- Pd-mediated transfer hydrogenation of carbonyl compounds is demonstrated

A novel NHC-palladium(II) (NHC = N-heterocyclic carbene) complex and its immobilised version have been prepared and fully characterised. Optimisation studies led to good catalytic activities in Suzuki-Miyaura cross coupling and chloroarene dehalogenation reactions. Furthermore, the unexpected palladium-mediated transfer hydrogenation of a carbonyl compound is reported.
