Web14 dec. 2024 · Iodination of an alkane is very slow and reversible because iodine is the least reactive halogen and HI produced in the first step reduces the alkyl halide back to … 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 …
WebBromo derivatives of alkanes are prepared by direct bromination. The reactivity order of abstraction of H atoms towards bromination of alkane is 3°H (tertiary) > 2°H (secondary) > 1°H (primary). Iodination and Fluorination. Direct iodination is not possible with iodine as the reaction is reversible.
