Solvent-free Markovnikov hydroamination of vinylarenes with carboxamides: a heterogeneous catalytic approach using Hβ zeolite†
The synthesis of carbon–heteroatom bonds, a crucial element in organic chemistry, often requires obstacles in direct amine integration with olefins. This study introduces a sustainable approach for producing nitrogen-bearing molecules through the Markovnikov hydroamination of vinylarenes with carboxamides, employing Hβ zeolite as an effective heterogeneous catalyst in a solvent-free environment. We explored the method's adaptability over various substrates, achieving consistently high yields and regioselectivity in the resultant products. The procedure's scalability to gram-level production and the catalyst's sustainable reuse for multiple cycles (up to five) underscores its viability for industrial application, indicating a significant increase in organic synthesis activity.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
