E- and Z-, di- and tri-substituted alkenyl nitriles through catalytic cross-metathesis was written by Mu, Yucheng;Nguyen, Thach T.;Koh, Ming Joo;Schrock, Richard R.;Hoveyda, Amir H.. And the article was included in Nature Chemistry in 2019.Synthetic Route of C8H9IO2 This article mentions the following:
Molybdenum alkylidene complexes (either molybdenum-based monoaryloxide pyrrolides or chlorides) were used as catalysts for the diastereoselective olefin metathesis reactions of alkenes with acrylonitrile, maleonitrile, or fumaronitrile to provide (E)- or (Z)-α,β-unsaturated nitriles and trisubstituted α,β-unsaturated nitriles. Oleyl alc. and oleic acid underwent stereoselective cross-metathesis with maleonitrile using pinacolborane or bis(triisopropylphenyl)borane as in-situ protecting group reagents. Intermediates toward the synthesis of natural products and pharmaceuticals were prepared using these methods. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Synthetic Route of C8H9IO2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Synthetic Route of C8H9IO2
