Improved Fischer esterification of substituted benzoic acid under sealed-vessel microwave condition

Improved Fischer esterification of substituted benzoic acid under sealed-vessel microwave condition

Ethyl-4-fluoro-3-nitro benzoate was synthesised in good yield under closed vessel conditions using a single-mode microwave. This simple method involved adding catalytic amounts of H2SO4 at specific intervals of time to overcome the problems associated with equilibrium. The method was first optimised...
