Kinetics for dichlorocyclopropanation of 1,7-octadiene under the influence of ultrasound assisted phase-transfer catalysis conditions

Ultrasonically Promoted Synthesis of Ethyl 2-(naphthalen-2-yloxy)acetate in Solid-Liquid Heterogeneous Phase Transfer Catalysis Condition

“…The increase in the conversion or rate of the reaction was mainly attributed to the synergistic effect of ultrasound, i.e. induce the surface area, change the size, and morphology of phase-transfer catalyst [29][30][31]. Further, the opportunity of collision between active intermediate and reactant present in the organic phase is increased by increasing catalyst concentration.…”

Recent Strategies in Organic Reactions Catalyzed by Phase Transfer Catalysts and Analyzed by Gas Chromatography

“…Further, it is favorable for the reaction in choosing quaternary ammonium salts of larger carbon numbers. The reason is that the lipophilicity is strong using the quaternary ammonium salts of larger carbon number (Wang & Rajendran, 2007b, 2007cWang & Chen, 2008). …”

“…Phase transfer catalysis will be of curiosity to anyone working in academia and industry that needs an up-to-date critical analysis and summary of catalysis research and applications. Presently, ingenious new analytical and process experimental techniques viz., ultrasound and microwave irradiation assisted PTC transformations (Masuno et al, 2005;Wang & Rajendran, 2006;Wang & Rajendran, 2007a, 2007bWang & Chen, 2008;. Wang & Chen, 2010;Vivekanand & Wang, 2011;Yang & Lin, 2011;Chatti, et al, 2002;Gumaste et al, 2004;.…”

Ultrasound Methodology for the Synthesis of 2-(4-nitrophenyl)-phenylacetonitrile with Phase-Transfer Catalysis Condition ? A Kinetic Study

“…The cannizzaro reaction catalyzed by a phase-transfer catalyst under ultrasonic wave of 20 KHz dramatically accelerated the reaction [14]. Licensed Under Creative Commons Attribution CC BY dichlorocyclopropanation of 1,7-octadiene was reported using benzyltriethylammonium chloride as catalyst assisted by ultrasound irradiation, giving the reaction rate greatly accelerated [15]. The reaction of oximes and dicholoromethane by PTC assisted by ultrasound got 95% in the silence condition was 16h [16].…”
