I found the field of Chemistry very interesting. Saw the article Modular Dual-Tasked C-H Methylation via the Catellani Strategy published in 2019. Category: nitriles-buliding-blocks, Reprint Addresses Zhou, QH (corresponding author), Wuhan Univ, Engn Res Ctr Organosilicon Cpds & Mat, Sauvage Ctr Mol Sci, Coll Chem & Mol Sci,Minist Educ, Wuhan 430072, Peoples R China.; Zhou, QH (corresponding author), Wuhan Univ, Inst Adv Studies, Wuhan 430072, Peoples R China.. The CAS is 95-11-4. Through research, I have a further understanding and discovery of 5-Norbornene-2-carbonitrile
We report a dual-tasked methylation that is based on cooperative palladium/norbornene catalysis. Readily available (hetero)aryl halides (39 iodides and 4 bromides) and inexpensive MeOTs or trimethylphosphate are utilized as the substrates and methylating reagent, respectively. Six types of ipso terminations can modularly couple with this ortho C-H methylation to constitute a versatile methylation toolbox for preparing diversified methylated arenes. This toolbox features inexpensive methyl sources, excellent functional-group tolerance, simple reaction procedures, and scalability. Importantly, it can be uneventfully extended to isotope-labeled methylation by switching to the corresponding reagents CD3OTs or (CH3OTs)-C-13. Moreover, this toolbox can be applied to late-stage modification of biorelevant substrates with complete stereoretention. We believe these salient and practical features of our dual-tasked methylation toolbox will be welcomed by academic and industrial researchers.
