Air and moisture stable robust bio-polymeric palladium catalyzed Csingle bondC bond formation and its application to the synthesis of fungicidal
Cellulose supported bio-heterogeneous polymeric Pd(II) catalyst, stable to air and moisture, was designed and characterized with different spectroscopic techniques including FESEM, TEM, XPS, XRD, ICP-AES and EDX. The Pd(II) catalyst showed high catalytic performance (0.2 to 0.0009 mol%) to the Suzuki-Miyaura Csingle bondC cross-coupling reaction of aromatic halides and aryl diazonium salts with a range of organoboronic acids to produce the respective biaryl product in up to 97% yield. Biologically active Boscalid, a fungicide that effectively inhibits the growth of fungal pathogens like ascomycetes on fruits and plants, could also be constructed through using this catalyst. Additionally, it was possible to recover the Pd(II) catalyst from the reaction medium and reused it repeatedly without significantly degrading its catalytic efficiency.
