Catalysed esterifications in room temperature ionic liquids with acidic counteranion as recyclable reaction media

Ionic liquid promoted synthesis of bis(indolyl) methanes

“…The catalyst [bnmim] [HSO 4 ] was prepared according to literature methods [11]. The completion of reactions was monitored by TLC and products were identified by comparing melting points with those found in literature and spectral analysis [23][24][25][26][27] …”

Preparation of α-Bromoketones and Thiazoles from Ketones with NBS and Thioamides in Ionic Liquids

“…Ionic liquids offer interesting and useful features that are advantageous to organic reactions such as negligible vapor pressure, nonflammability, high thermal stability, and easy reusability. In this regard, ionic liquids have been successfully used in the Friedel-Crafts reaction [31][32][33], hydrogenation [34][35][36], Diels-Alder reactions [37][38][39], Mizoroki-Heck, Suzuki-Miyaura, Sonogashira, and olefin metathesis reactions [40][41][42][43][44], Michael additions [45], oxidation [46][47][48][49][50][51][52][53][54], condensation reaction [55][56][57][58][59], formation of imines [60], 1,2-rearrangement [61], esterification of carboxylic acids and carboxylates [62][63][64][65], Williamson ether synthesis [66][67][68][69][70][71][72], and the Grignard reaction [73,74]. We have reported efficient methods for the esterification of carboxylic acids and phosphonic acids with trialkyl orthoacetate in ionic liquid <...>…”

Esterification process to synthesize isopropyl chloroacetate catalyzed by lanthanum dodecyl sulfate

“…There is a global effort to replace the conventional catalysts by eco-friendly catalysts. The replacement of current chemical processes with more environmentally benign alternatives is an increasingly attractive subject (Fraga-Dubreuil et al, 2002;Qian et al, 2011).…”
