A theoretical study of the IEDDA reaction of endo-BCN with 2H-pyran-2-one, 2H-thiopyran-2-one, 2H-pyran-2-thione and 2H-thiopyran-2-thione reveals the superior reactivity of 2H-pyran-2-thiones because of the lower distortion energy.
In this review, we provide a comprehensive overview of the synthesis of thiopyran family compounds via cycloaddition reactions, with examples spanning from the year 2000 to the present.
While freezing a double-emulsion, sudden topological transitions of compound droplets are observed caused by partial solidification, triggering liquid-to-vapor phase transitions.
Depending on the direction of the Marangoni effects, gas bubble locations and consequently the force balance determining gas bubble detachment can vary significantly.
Green synthesis of CoFe2O4 magnetic nanoparticles mediated by petai peel extract (PPE) as a nanocatalyst for the synthesis of thiazolidinedione-based chalcone 4H-thiopyran.
