De, Pinaki Bhusan; Pradhan, Sourav; Banerjee, Sonbidya; Punniyamurthy, Tharmalingam published the article 《Expedient cobalt(II)-catalyzed site-selective C7-arylation of indolines with arylboronic acids》. Keywords: phenyl pyrimidinyl indoline regioselective preparation; indoline arylboronic acid arylation cobalt catalyst.They researched the compound: 5-Fluoroindoline( cas:2343-22-8 ).HPLC of Formula: 2343-22-8. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:2343-22-8) here.
A series of 7-phenyl-1-pyrimidin-2-yl-indolines I [R1 = H, 2-Me, 3-Cl, etc.; R2 = H, 5-OMe, 4-Br, etc.; R3 = H, 2-Me, 3-Me] was prepared via cobalt catalyzed site-selective C7-arylation of indolines with arylboronic acids using Mn(OAc)2·4H2O as an oxidant.
When you point to this article, it is believed that you are also very interested in this compound(2343-22-8)HPLC of Formula: 2343-22-8 and due to space limitations, I can only present the most important information.
