Esters are common chemicals with extensive applications in medicine, biology,\nchemistry, and material sciences [1]-[7]. Esters used not only as solvents but also\nare in perfumes, essential oils, agriculture and food flavorings, antioxidant, plastics,\ndetergents, and for many other purposes. Isoamyl acetate (odor of banana),\nethyl butanoate (odor of mango), methyl 2-methylbutanoate (odor of pineapple),\nvitamin C, cocaine, etc., are some common interesting examples occurring\nin the nature. The enormous use of transition metal complexes to activate organic\nmolecules makes them viable visions for developing catalytic processes\nwith high selectivity and atom economy. This work focusses to find a facile way\nof making esters by microwave irradiated cross-coupling reaction of carboxylic\nacids, allyl type halides, in the presence of palladium-catalyst (Scheme 1) and\napply that effective cross coupling method to synthesize arachidonic acid esters,\nand folic acid esters, etc.
