Ultrasound-promoted Catalyst-free Synthesis of α-Aminonitriles in 1-Butyl-3-methylimidazolium Bromide ([Bmim]Br) as a Reusable Neutral Ionic Liquid
A catalyst-free one-pot three component methodology for the synthesis of α-aminonitriles under ultrasonic irradiation at room temperature using [Bmim]Br as a neutral reaction medium is described. A broad range of substrates including the aromatic, heteroaromatic and aliphatic aldehydes were condensed with amines (aliphatic and aromatic) and trimethylsilyl cyanide (TMSCN). Using this method, all...
متن کاملMagnetic Ionic Liquid Functionalized Sulfonic Acid: a Green and Efficient Catalyst for the One-pot Synthesis of 1-Amidoalkyl-2-Naphtols
In this study, a novel acidic magnetic dicationic ionic liquid was prepared in three steps to serve as a green catalyst in organic synthesis. The newly synthesized catalyst was characterized UV- VIS, and VSM analysis. Additionally, the decomposition steps acatalyst were investigated by thermal analysis techniques (TGA/DSC). The synthesized acidic magnetic dication...
متن کاملLactic acid, as an efficient catalyst for the one-pot three-component synthesis of 1-amidoalkyl-2-naphthols under thermal solvent-free conditions
For the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. We have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...
