Web26 aug. 2002 · The classical synthesis of alkyl iodides from alkenes and hydrogen iodide often leads to low yields and side reactions due to uncontrollable iodine liberation. 1 Consequently, several alternative approaches to hydroiodination have been developed: 2 chlorotrimethyl silane/sodium iodide/water, 3 iodine/alumina, 4 borane-N,N-diethylaniline … Web28 mrt. 2024 · In view of this situation, we became interested in developing the iodination of terminal alkynes as an alternative approach to prepare radio-iodinated probes. In particular, we envisioned that this reaction could be highly chemoselective even in the presence of electron rich aromatic and heteroaromatic rings as well as electron rich alkenes.
