Mechanism for iodination of acetone
WebThe iodination of acetone is a simple and measurable reaction, it proceeds from yellow to colorless. The observable color change is slow enough to measure in minutes, but not too slow that it will exceed a lab class period. We can use the following equation to calculate the rate of this reaction. WebKetone halogenation. In organic chemistry, α-keto halogenation is a special type of halogenation . The reaction may be carried out under either acidic or basic conditions in an aqueous medium with the corresponding elemental halogen. In this way, chloride, bromide, and iodide (but notably not fluoride) functionality can be inserted selectively ...
