WebIn this work, a novel renewable taurine-based ionic liquid (IL), [TauIm][HSO4], was synthesized via the Debus–Radziszewski reaction. The synthesized IL was then used to produce ethyl levulinate (EL) from several lignocellulosic substrates under microwave irradiation. Experimental conditions (temperature, time, and IL quantity) for EL production … WebJun 16, 2024 · Paul Crookston. June 16, 2024.

WebJun 3, 2024 · The Debus–Radziszewski imidazole synthesis was adapted to directly yield long-chain imidazolium ionic liquids. Imidazolium acetate ionic liquids with side-chains up to sixteen carbon atoms were synthesised in excellent yields via an on-water, one-pot reaction. The imidazolium acetate ILs acted as surfactants when d Liquid Crystals … WebDec 21, 2024 · The modified Debus–Radziszewski reaction was used to design and synthesize novel truxene derived blue-emitting materials bearing phenanthroimidazole substituents. The materials were prepared non-catalytically under ambient conditions using a triamino based derivative of truxene as a key precursor in good yields. The 5, 5′, 10, …
WebThe construction of boron-containing COFs rapidly evolved by variating the synthetic conditions employed by several researchers. For example, Cooper and co-workers showed that reaction times can be dramatically shortened by using microwave heating, which also helps in the cleaning step of boron-containing COFs.

The desired products were obtained with highly regioselectivities under mild conditions.
WebIn 1858, Debus first synthesized imidazole from glyoxal, ammonia, and formaldehyde. The Debus synthesis was later often commented by the Polish chemist Bronisław Leonard Radziszewski. Therefore, this reaction is sometimes called "Radziszewski reaction". He was elected a Fellow of the Royal Society in 1861. References
