TCI offers a wide selection of fine and specialty chemicals by drawing upon expert manufacturing techniques. With an extensive catalog of 29,000 high quality organic reagents suitable for benchtop-to-bulk chemistry. This issue features our bench-stable fluoroalkylating agents, a useful catalyst for Balz-Schiemann fluorination, our TCIMAIL Research Article on Asymmetric Synthesis of Axially Chiral Compounds by Rhodium(I)-Catalyzed [2+2+2] Cycloaddition, and more.
Bench-stable Crystalline Fluoroalkylating Agents

Bench-stable Crystalline Fluoroalkylating Agents

Sulfonium salts are useful reagents for fluoroalkylation. The trifluoromethylating agent (Umemoto's Reagent II) [D5335] affords trifluoromethylated products from various substrates. The difluoromethylating agent [D5630] is suitable for metal-free photoredox-catalyzed difluorometylation. Additionally, these solid reagents are bench-stable and easy-to-handle.

Balts-Schiemann Fluorination

Hypervalent Iodine-Catalyzed Balz–Schiemann Fluorination

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 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.
