A cascade Suzuki-Miyaura cross-coupling gave rise to 9,10-dihydrophenanthrenes I [R1 = n-Pr, n-hexyl, (CH2)2Ph, etc.; R2 = H, 3-Me, 2-F, etc.; R3 = H, 6-Me, 7-F, etc.] was developed. Using biaryls with unsym. substitution-pattern full site-selectivity was observed Furthermore, this cross-coupling of an alkyl 1,2-bisboronic pinacol ester proceeded through the challenging coupling of a secondary boronate with complete stereoretention. The experimental process involved the reaction of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Recommanded Product: 258278-25-0)

The article was titled 《C-X (X = N, O) cross-coupling reactions catalyzed by copper-pincer bis(N-heterocyclic carbene) complexes》. The information in the text is summarized as follows:

The application of these complexes in Ullmann-type C-X (X = N, O) coupling of azoles such as 1H-imidazole, benzimidazole, pyrazole and phenols such as phenol, p-cresol with aryl halides ArI (Ar = Ph, 1-phenylethan-1-one, 2-methylphenyl, etc.) in a relatively short reaction time has been reported. In contrast to other well-defined copper(I) catalysts that require an inert atm. for an efficient C-X coupling, the employed Cu(I)-pincer bis(NHC) complexes provide good to excellent yields in air. The air-assisted reactivity, unlike that in the Sonogashira reaction, is also affected by the base employed and the reaction time. With Cs2CO3 and K2CO3, the oxygen-generated catalyst is more reactive than the catalyst formed under argon in a short reaction time (12 h). However, the difference in reactivity is compromised after a 24 h reaction with K2CO3. The efficient pincer Cu-NHC/O2/Cs2CO3system provides great to excellent cross-coupling yields for electronically diverse aryl iodides and imidazole derivatives The catalyst scope is controlled by a balance between nucleophilicity, coordinating ability, and steric hindrance of aryl halides and N-/O-nucleophiles. In the experiment, the researchers used 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Related Products of 258278-25-0)

Recommanded Product: 258278-25-0. The article was titled 《Hydrogen bonding-enabled gold catalysis: ligand effects in gold-catalyzed cycloisomerizations in hexafluoroisopropanol (HFIP)》. The information in the text is summarized as follows:

Gold catalysis has witnessed immense evolution in recent years, yet it still requires the use of activators to render the common [AuCl(L)] complexes catalytically active. Herein, the H-bonding donor properties of hexafluoroisopropanol (HFIP) are utilized for Au-Cl bond activation and the ancillary ligand and counteranion effects on cycloisomerization reactions are showcased in HFIP as solvent.
