Selective iodination of 2-acetyl-1-naphthol using iodine and iodic acid under solvent-free grinding technique

A highly selective fluorescent chemosensor for cyanide anions based on a chalcone derivative in the presence of iron(iii) ions, and its capacity for living cell imaging in mixed aqueous systems

“…The fluorescence and bright-field images reveal that the fluorescence signals were localized in the perinuclear area of the cytosol, indicative of a subcellular distribution due to the high cell membrane permeability of 1-Fe 3+ . 39,40 These results demonstrate that the 1-Fe 3+ complex is cell membrane permeable and can also be used for the imaging of CN À in living cells and potentially in vivo.…”

A Facile, Mechanochemical, Solvent-, and Catalyst-Free Synthesis of Functionalized 4-Thiazolidinones

“…On the other hand, mechanochemical synthesis is emerging as new green method for the preparation of various heterocycles via C-O, C-N, and C-S bond formation through methods like grinding and sonication. [11][12][13][14][15][16][17][18] The simple economical method offers several benefits such as less use of harmful toxic solvents, use of eco-friendly chemicals, less use of toxic and expensive metal-based catalyst, lesser release of harmful wastes and no or negligible byproduct formation. [19][20][21] Since the reaction does not result in the formation of any byproduct, the yield of the reaction is also remarkably higher as compared to conventional methods employed.…”

“…Keeping in mind, the biological activities of 4thiazolidinones, 1-8 (Figure 1) and realizing the importance of the green methodologies in organic synthesis, it was thought worthwhile to explore the greener methods for the preparations of functionalized 4-thiazolidinones. On the other hand, mechanochemical synthesis is emerging as new green method for the preparation of various heterocycles via C-O, C-N, C-S bond formation through methods like grinding, sonication [11][12][13][14][15][16][17][18] . The simple economical method offers several benefits such as less use of harmful toxic solvents, use of eco-friendly chemicals, less use of toxic and expensive metal-based catalyst, lesser release of harmful wastes and no or negligible by-product formation [19][20][21] .…”

X-Ray Powder Diffraction Data for a New Thiophene Chalcone Obtained by a Claisen-Schmidt Reaction

“…Heterocyclic chalcones are conventionally synthesized by Claisen-Schmidt condensation reaction in which aldehyde reacted with acetophenone in the presence of aqueous alkaline bases (Rao et al, 2004;Kumar et al, 2013b). Chalcones have also been synthesized using Friedel-Crafts acylation (Nasir et al, 2013), microwave irradiation (Jayapal and Sreedhar, 2010), ultrasonic irradiation (Li et al, 2002), grinding technique (Zangade et al, 2011) and by Suzuki coupling reaction (Eddarir et al, 2003).…”
