N-Hydroxylation is not restricted to amines or amides. Other nitrogen-based functional groups that have at least one N–H bond are susceptible tocytochromeP450-catalyzedN-hydroxylation. Examples include the amidino group of theantiprotozoal drugpentamidine(86)131(eqn[31]), theguanidino groupof the...

Direct and highly selective conversion of benzylic, allylic and propargylic TMS, TBDMS and THP ethers into their corresponding iodides with the SiO2–Cl/NaI system is described. Reactions were conducted in CH3CN at room temperature. Aliphatic silyl and tetrahydropyranyl ethers remained almost intact ...
