Green one-pot multicomponent synthesis of pyrrolidinones using planetary ball milling process under solvent-free conditions Nader Ghaffari Khaligh Taraneh Mihankhah Mohd Rafie Johan 10.6084/m9.figshare.8003723.v2 https://tandf.figshare.com/articles/journal_contribution/Green_one-pot_multicomponent_synthesis_of_pyrrolidinones_using_planetary_ball_milling_process_under_solvent-free_conditions/8003723 <p>This paper presents a novel and efficient protocol for the synthesis of pyrrolidinones using catalytic loading of 1,1'-butylenebis(3-sulfo-3H-imidazol-1-ium) hydrogen sulfate as a recyclable Brönsted acid ionic liquid through ball milling process at room temperature under solvent-free conditions. The developed method provides good to excellent yields of various pyrrolidinones in environmentally friendly conditions. Furthermore, this efficient protocol displays a combination of the synthetic advantage of one-pot multicomponent reaction with ecological benefits and convenience of a mechanochemical procedure.</p> 2020-02-10 12:29:02 Mechanochemistry pyrrolidinone ionic liquid Brönsted acid eco-friendly conditions
