Web31 jul. 2024 · The way to achieve direct iodination in the absence of powerful activating substituent groups is to convert molecular iodine to some more active species (perhaps H 2OI ⊕ or I ⊕) with an oxidizing agent such as nitric acid or hydrogen peroxide: I 2 + 4HNO 3 → 2H 2O − I + + 2NO 2 + 2NO − 3 I 2 + H 2O 2 + 2H + → 2H 2OI + Web21 jan. 2024 · examine the mechanism of iodination of aromatic contaminants, e.g., dipeptides and phenols. Computational prediction of the energy barriers of the formation of iodinated tyrosylglycine (I-Tyr-Gly) (66.9 kcal mol−1) and hydroxylated Tyr-Gly (OH-Tyr-Gly) (46.0 kcal mol−1) via iodination with HOI favors the formation of OH-Tyr-Gly over I-Tyr-Gly.
Web16 mrt. 2024 · The Sharpless asymmetric epoxidation of allylic alcohol provides a powerful tool for the synthesis of optically active epoxy alcohol. For example, hexe-2-en-1-ol undergoes epoxidation to give chiral epoxy alcohols with 94% ee and 85% yield in presence of 5-10 mol% of Ti (O i Pr) 4 , L- (+)-DET and t -BuOOH (Scheme 5.2. 1 ).

PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids. Similar to or the same as: C r O 3 and pyridine (the Collins …
Webbond underwent iodination in an excellent yield but accompanied by allylic rearrangement. The method can be applied easily for the conversion of primary and secondary saturated alcohols into their iodides in excellent yields (Table 1, entries 10–13). We also studied the iodination of 1-adamantanol as an example of a ter-tiary alcohol.
