The efficient Pd-catalyzed double-fold C-H oxygenation of arenes into resorcinols e. g., I using the newly developed 2-pyrimidyldiisopropylsilyl (PyrDipSi) directing group is described. Its use allows for the sequential introduction of OAc and OPiv groups in a one-pot manner to produce orthogonally protected resorcinol derivatives The PyrDipSi group is superior to the previously developed 2-pyridyldiisopropylsilyl (PyDipSi) group, as it is efficient for monooxygenation of ortho-substituted arenes. Notably, the PyrDipSi group can be easily installed into arene mols. and can be easily removed or modified after the oxygenation reaction. In the experiment, the researchers used many compounds, for example, N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8Recommanded Product: 77350-52-8).
N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Recommanded Product: 77350-52-8
