I found the field of Chemistry very interesting. Saw the article DMAP and PivOH-promoted amination/allenization reaction published in 2020. Product Details of 177-11-7, Reprint Addresses Liang, YM (corresponding author), Lanzhou Univ, State Key Lab Appl Organ Chem, Lanzhou 730000, Peoples R China.. The CAS is 177-11-7. Through research, I have a further understanding and discovery of 1,4-Dioxa-8-azaspiro[4.5]decane
This report described the first DMAP and PivOH-promotedortho-C-H amination andipso-allenization reaction of iodobenzenes realized by Pd/norbornene cooperative catalysis. Based on control experiments and DFT calculations, we speculated that the three ligands have different functions and mechanism paths in the reaction.
Product Details of 177-11-7. About 1,4-Dioxa-8-azaspiro[4.5]decane, If you have any questions, you can contact Zhang, BS; Li, YK; Gou, XY; Zhang, Z; An, Y; Wang, XG; Liang, YM or concate me.
