Rhodium Catalyst for cis-Selective Hydrogenation of Aromatic Rings
With CAAC (Cyclic(Amino)(Alkyl)Carbene)-rhodium complex [C3592] having a strong σ-donating ligand, it's widely used as an efficient and selective aromatic hydrogenation catalyst. Key features of C3592 include use in the synthesis of cyclohexane moieties, while still retaining various functional groups like carbonyls, silyls, and boryls in a single step. Under these conditions, the cis-configured saturated hydrocarbon is selectively given.
Understanding the fundamental reactions of organic chemistry is paramount to successful research. New and senior chemists benefit from reviewing the cornerstones of synthetic chemistry and the various reagents required to be successful in the lab. Not only do these reactions appear in every synthetic endeavor, they inspire new innovations and reactions based off their fundamental principles. To assist our global research colleagues, TCI has recently prepared a small list of essential named reactions, such as the Grignard and Vilsmeier-Haack reactions, for easy reference with the necassary reagents required.
Highly Air-stable Manganese Catalyst Usable for Versatile Hydrogenations
A highly air-stable manganese complex with pincer ligands, Bromodicarbonyl[bis[(2-diisopropylphosphino)ethyl]amine]manganese(I) [B5670] can catalyze various hydrogenation reactions such as nitrile reduction, but also is applicable to the transfer of hydrogenation reactions using IPA as a hydrogen source. Additionally, we expect B5670 as an alternative to precious metal catalysts.
Aziridine Derivative for the Synthesis of a Trifluoroalkylamine Moiety
Useful in the synthesis of trifluoroalkylamine derivatives, its been reported that 1-tosyl-2-(2,2,2-trifluoroethyl)aziridine [T3795] reacts with various carbon and nitrogen nucleophiles to provide ring-opening adducts with high regioselectivity and in high yields. Furthermore, when the indole adduct is treated with acetaldehyde, the tetrahydroharmine derivative containing a fluorinated functional group is afforded via a Pictet-Spengler reaction.
