Satake, Akiharu published the artcileNovel η3-Allylpalladium-Pyridinylpyrazole Complex: Synthesis, Reactivity, and Catalytic Activity for Cyclopropanation of Ketene Silyl Acetal with Allylic Acetates, Safety of Ethyl 2,2-dimethylpent-4-enoate, the main research area is allyl palladium pyridinyl pyrazole preparation catalyst; cyclopropanation ketene silyl acetal allylic acetate; catalysis cyclopropanation ketene silyl acetal allylic.
Novel cationic η3-allylpalladium-pyridinylpyrazole complexes I (R = Me, But) were synthesized from 3-alkyl-5-(2-pyridinyl)pyrazole and η3-allylpalladium chloride dimer in the presence of AgBF4. Cationic complexes I were converted into neutral complexes II under basic conditions. These complexes were characterized by 1H, 13C, and 15N NMR studies. Neutral complexes II have high catalytic activity for cyclopropanation of ketene silyl acetals with allylic acetates. Comparison of the cationic and neutral complexes and the reaction mechanism of cyclopropanation were discussed.
Journal of the American Chemical Society published new progress about Cyclopropanation. 86549-27-1 belongs to class esters-buliding-blocks, name is Ethyl 2,2-dimethylpent-4-enoate, and the molecular formula is C9H16O2, Safety of Ethyl 2,2-dimethylpent-4-enoate.
