Synthesis of (alkynyl)phenylporphyrins by palladium-catalyzed cross-coupling reactions was written by Chan, Kin Shing;Chan, Chi Shing. And the article was included in Synthetic Communications in 1993.Electric Literature of C47H36N4O The following contents are mentioned in the article:
Title compounds I (R = 3-, 4-Cú·CR1, R1 = SiMe3, Ph, Bu) and the Zn complex of I (R = 4-Cú·CSiMe3) were prepared by converting I (R = OH) to the triflates and treating these with R1Cú·CSnBu3. I (R = Cú·CSiMe3) were also obtained with HCú·CSiMe3. I (R = Cú·CH) were obtained from I (R = Cú·CSiMe3). This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Electric Literature of C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. The atoms and molecules used as ligands are almost always those that are capable of functioning as the electron-pair donor in the electron-pair bond (a coordinate covalent bond) formed with the metal atom. The ability of ligands to engender a variety of useful properties of organometallic complexes is the major enabling force for the discovery of new catalytic reactions, activation of small molecules, dramatically enhanced reactivity.Electric Literature of C47H36N4O
