Iodination of alkanes is reversible

WebIn the iodination, the addition of the electrophiles is now reversible, thus the subsequent deprotonation, proceeding via TS2, is the rate‐ and selectivity‐determining step. This step dictates the regioselectivity since restoring planarity in the corresponding C5‐TS2 results in increased A 1,3 strain between the enamine carbon substituent and the iodide (not … Web25 okt. 2024 · Iodination of alkanes is reversible reaction,as HI so produced is stronger reducing agent,it attacks on Alkyl iodides produced.Hence backward reaction is …
