Green Chemistry
This experiment also demonstrates some of the principles of green chemistry (2):performing less hazardous chemical synth- eses,using safer solvents,and using safer chemistry to reduce accidents.These reactions involve bleach,a household chemical,as the reagent.This reagent is safer to handle than other oxidants and halogenating agents,such as chromium- and manganese- based reagents,gaseous chlorine or liquid bromine,sulfuryl chloride,and 2-iodoxybenzoic acid (7).The reactions are con-ducted using water and acetic acid as the only solvents,and no organic solvent is required to work up or extract the products.The electrophilic aromatic substitution does not require a Lewis acid promoter.Although this experiment demonstrates only a few of the principles of green chemistry,it is greener than the alternatives of using harsher reagents or additional solvents (8).
