The ionic liquid (IL), tetrabutylphosphonium trifluoroacetate ([P4444][CF3COO]), showed a low critical solution temperature (LCST)-type phase transition in water. Using this temperature-sensitive IL and the Triton X-100/H2O system, the reversible transformation between micelles and microemulsions was thus realized by a thermal stimulus for the first time.
Reaction of a variety of dienynes with bis(pinacolato)diboron catalysed by Pd bis(trifluoroacetate) affords allylic boronates containing five or six membered carbo- or heterocycles, by concomitant formation of one C-C and one C-B bonds. Resulting allylboronates can be employed for a variety of subsequent transformations.
Celecoxib is a non-steroidal anti-inflammatory drug used in the treatment of pain and inflammation. The objective of this study is to synthesize p-chlorocelecoxib by the condensation of 4-methylacetophenone and ethyl trifluoroacetate, followed by reaction with 4-(2-chlorohydrazinly)benzenesulfanimide & identification of celecoxib analogue through several analytical methods like UV visible, IR, ...
New classes of acidic or basic ionic liquids (ILs) are gaining special attention, since the efficiency of many processes can be enhanced by the judicious manipulation of these properties. The absorption of sour gases can be enhanced by the basic character of the IL. The fluorination of the cation or the anion can also contribute to enhance the gas solubility. In this work these two characterist...
We describe palladium-catalyzed carbocyclization of 1,6-enynes leading to six-membered rings by water-originated hydride addition. Mechanistic features of this anomalous carbocyclization and isolation of a chiral five-membered C-Pd intermediate as an oxidized form of trifluoroacetate are also reported.
