1-Fluoro-3,3-dimethyl-1,2-benziodoxole [F0957] is a useful catalyst for Balz?Schiemann reactions. In the presence of catalytic amount of [F0957] and BF3·OEt2 [B0527], aryl diazonium tetrafluoroborate salts react at r.t. - 60 °C to afford the corresponding fluorinated aryl products in good yields. This reaction can proceed at a lower temperature than conventional Balz-Schiemann reactions and is applicable to various compounds bearing electron-withdrawing groups such as esters, as well as heteroarenes.
TCIMAIL is turning 50! TCIMAIL contains technical papers contributed by leading professors and scientists featuring TCI products. We invite you to read back issues that contain various scientific articles from prominent researchers. Be on the lookout for our 50th Anniversary issue coming in 2019!
TCIMAIL Research Article: Asymmetric Synthesis of Axially Chiral Compounds by Rhodium(I)-Catalyzed [2+2+2] Cycloaddition
In the recently released TCIMAIL, we feature Professor Ken Tanaka's resarch article, "Asymmetric Synthesis of Axially Chiral Compounds by Rhodium(I)-Catalyzed [2+2+2] Cycloaddition." The use of cationic rhodium(I)/axially biaryl bisphosphine complexes as catalysts allows for the highly efficient enantioselective biaryl synthesis to occur. Also discussed is the enantioselective synthesis of axially chiral compounds with non-biaryl axial chirality and the diastereoselective biaryl synthesis.
The ceremony of “TCI Organic Synthesis Award”, December 2018 in Taiwan
The Second “TCI Organic Synthesis Award” ceremony was held at the Chinese Chemical Society Located in Taipei (CCS Taipei) annual meeting in Taiwan on December 8, 2018. This award is established by TCI together with CCS Taipei and is given to the student in organic synthesis research field who is chosen as the winner in the graduate student thesis competition (includes dissertation and academic study achievements) of the CCS Taipei annual meeting.
TCI will keep on supporting researchers to contribute the development of science.
