Ionic Liquids (ILs) have been frequently used as a green solvent in place of The application of ILs as solvent and catalyst has reported for a variety of functional group transformation. Ionic liquids usually possess unique properties, such as non-volatility, non-flammability and low melting point, negligible vapor pressure and talent to dissolve many organic and inorganic compounds. Recently ILs have been successfully employed as dual reagent (solvents+ catalytic) for a variety of reactions, but their use as catalyst under solvent-free conditions need to be given more attention. In recent years, many types of reactions have been investigated in IL, therefore here in our continuation for developing green methods in organic synthesis, we wish to report the synthesize and characterization of morpholinium chloride as a novel ionic liquid and its application in some organic reactions. Protected hydroxyl functionalities are very important intermediates due to their organic and analytical chemistry. Many multi-step syntheses in organic reactions include at least one-step of alcohol group protection. In this regard, one of the most common strategies is to convert alcohols into their corresponding tetrahydropyranyl (THP) ethers. The THP ethers are attractive, because their straightforward preparation and less expensive and also stability under different conditions such as strong basic media, Grignard reagents and organometallic reagents. In this project a mild procedure for protection of alcohols with 3, 4-dihydro-2H-pyran at room temperature in the presence IL under solvent-free condition has been investigated. Organic halides are talent intermediates in organic synthesis. They react with nucleophiles, such as amines or alkoxides, to give the corresponding substituted products. They are often used for in C-C bond formation via radical or substitution reactions. Although alkyl chlorides are often used but alkyl chlorides are less reactive than alkyl bromides or iodides. Thus, an efficient and practical protocol for the preparation of alkyl bromides also has been studied employing this ionic Liquid. Oxidation is a fundamental transformation in organic synthesis and there are numerous methods reported in the literature. Potassium permanganate (KMnO 4 ) has been used as an oxidant. Here also we in oxidation of primary and secondary benzylic alcohols were converted to their corresponding carbonyl compound by using KMnO 4 in the presence of morpholinium chloride as IL in acetonitrile under refluxing conditions. The projects have several major advantages such as using inexpensive material, mild reaction conditions, short reaction times and good to high yields.
