A novel palladium(II) carboxymethylcellulose (CMC-PdII) was prepared from sodium carboxymethylcellulose (CMC-Na) and PdCl2 in aqueous solution. It was employed as precatalyst for Heck-Matsuda and Suzuki-Miyaura couplings. The true catalytic species are active soluble Pd(0) or Pd(0) clusters released from palladium nanoparticles deposited on the CMC molecular skeleton (CMC-Pd0) formed in situ from CMC-PdII in the catalytic process.

A practical and general iron-catalyzed domino decarboxylation-oxidation of α,β-unsaturated carboxylic acids enabling aldehyde C-H methylation for the synthesis of methyl ketones has been developed. This mild, operationally simple method uses ambient air as the sole oxidant and tolerates sensitive functional groups for the late-stage functionalization of complex natural-product-derived and polyfunctionalized molecules.

Starch coated magnetic nanoparticles supported palladium catalyst has been explored to perform C–C cross coupling reactions, such as oxidative Heck coupling and Tsuji–Trost allylic coupling using organosilicon compounds as one of the coupling partners. The biopolymer coated magnetic catalyst was very easy to recover magnetically and was efficiently recycled in the subsequent batches. All the reactions were performed in air and thus the necessity of air and moisture free reaction condition is avoided. The present protocols show wide substrate scope and good yields of the products.
