Kohzadi H, Soleiman-Beigi M. Progress on the natural asphalt applications as a new class of carbonious heterogeneous support; synthesis of Na[Pd-NAS] and study of its catalytic activity in the formation of carbon-carbon bonds. Mol Divers 2021; 26:1957-1967. [PMID: 34505952 DOI: 10.1007/s11030-021-10306-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 08/26/2021] [Indexed: 10/20/2022]
Abstract
In continuation of our recent research on introducing natural asphalt as a new carbonious, eco-friendly, highly economical support, and also in addition to our plan to develop its application in heterogeneous catalyst chemistry, palladium grafted on natural asphalt sulfonate (Na [Pd-NAS]), was prepared and characterized using usual spectroscopy techniques. This new carbon-based heterogeneous nanocatalyst was successfully applied as an efficient catalyst for the Suzuki, Stille and Heck reactions under mild and sustainable conditions. The reaction of various aryl halides with triphenyltin chloride, phenylboronic acid or n-butyl acrylate provided the corresponding products with moderate to good yields. Na [Pd-NAS] was characterized by FT-IR spectroscopy, scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, inductively coupled plasma, thermogravimetric analysis techniques and N2 adsorption-desorption measurement. SEM image illustrated that the Na [Pd-NAS] has vermicular and flaky shapes. According to the IUPAC classiication, the sample exhibited IV type curves. More importantly, this ligand-free catalyst is stable under the reaction conditions. Besides, the catalyst was separated by simple filtration and reused for the several times without any deterioration in its activity. In this research we report Na[Pd-NAS] as a versatile and reusable nanocatalyst for the C-C coupling reactions.
