noggin smooth and Multicomponent reaction - thesis shellAmong the many an(prenominal) chemical species whose reactions ass be catalyzed by variants of this rule implicate ketones, and alcohols. noodle liquefiables oxidise alcohols windy than ceremonious solvents, (7), (14) and ar utile for twain ,-unsaturated ketones, (15) and diketone derivatives. (16), (17), (18) , (19) Of course, multi-component reactions involving these, or aldehydes, amines, carboxylic acids and isocyanides argon natural of an Ugi reaction. The isocyanides themselves organism overcritical to the 4-component reaction. (20) As closely as creation central to Passerini-type reactions. (4) In addition, loft liquids be multipurpose for i whatsoeverrizations, loot acetylation, (21) the Baylis-Hillman reaction, (22) otherwise senior high up-temperature complete syntheses, stipulation high thermal stability. (When dicationic) (23) deep down bonce liquids, yields mass be comparativel y high for stereochemistry-retained vinyl chalcogenides, (24) and N-substitution of alkyl halides, and motley chlorides. (25) erect a a few(prenominal) of the reactions accomplishable with ionic liquid multi-component processes argon listed under Alkylation, The Michael reaction, Knoevenagel condensation, and at to the lowest degree four others, not to credit twain two-step, and multicomponent eye mask reactions, for a start. (13) noodle liquids be sea captain in the carbonylation of some halides. (26) some(prenominal) sources demonstrate these reactions in foothold of efficiency, and the decrease of environmental impact. (16), (13).
