beta-type glycosidic bond formation by palladium-catalyzed decarboxylative allylation

The efficient and stereoselective construction of glycosidic linkages is of great significance in carbohydrate chemistry due to the ubiquitous existence of numerous biologically active natural products and saccharides. Although great efforts have been devoted to stereoselective glycosylations in the past few decades, constructing glycosidic bonds with high efficiency and selectivity remains a challenge and continues to be an important area in carbohydrate research. Phenols are widely used as nucleophiles in palladium-catalyzed allylation. In contrast, the possibility of using aliphatic alcohols as nucleophiles is not as thoroughly explored. The modified reaction conditions were then applied to other substrates. Originating from easily prepared carbonates, various glycosides, such as phenolic Oglycosides, thiophenolic S-glycoside, aliphatic O-glycosides, and even disaccharides, were synthesized in good yields by means of a palladium-catalyzed decarboxylative allylation.

Organometallic Fe?Fe Interactions: Beyond Common Metal?Metal Bonds and Inverse Mixed-Valent Charge Transfer

The compounds [Fe(CO)3(dRpf)]n+, n=0, 1, 2 and dRpf=1,1?-bis(dicyclohexylphosphino)ferrocene ([1]n+) or 1,1?-bis(diisopropylphosphino)ferrocene ([2]n+), were obtained as two-step reversible redox systems by photolytic and redox reactions. The iron?iron distance decreases from about 4 A to about 3 A on oxidation, which takes place primarily at the tricarbonyliron moiety. Whereas ferrocene oxidation is calculated to occur only in excited states, the near infrared absorptions of the mixed-valent monocations are due to an unprecedented ?inverse? inter-valence charge transfer from the electron-rich iron(II) in the ferrocene backbone to the electron-deficient tricarbonyliron(I). Protonation of complex 1 results in the formation of the structurally characterized hydride [1H]BF4, which reacts with acetone to form the dication, 12+, and isopropanol. While the hydride [2H]BF4was found to be unstable, protonation of 2 in acetone resulted in the clean formation of 22+,formally a hydrogen transfer.
