Palladium on carbon in PEG-400/Cyclohexane: Recoverable and recyclable catalytic system for efficient decarbonylation of aldehydes

A simple methodology for the decarbonylation of aldehydes catalysed by commercially available palladium on carbon in a green two-solvent system is reported. Various aromatic, aliphatic and heteroaromatic were transformed to corresponding decarbonylated products good yields. Product isolation from reaction mixture practice, catalyst can be reused three times.
