Two-coordinate silylamido complexes of nickel and copper rapidly react with CO to selectively form a new cyanate ligand along with hexamethyldisiloxane byproducts. Mechanistic insight into these reactions was obtained from the synthesis of proposed intermediates, several silyl- and phenyl- substituted amido analogues, and their subsequent reactivity with CO. These studies suggest that a unique intramolecular double silyl transfer step facilitates CO deoxygenation, which likely contributes to the rapid rates of reaction. The deoxygenation reactions create a platform for a synthetic cycle in which copper amido complexes convert CO to organic silylcarbamates.

A novel silver-catalyzed cascade radical isonitrile insertion and defluorinative cyclization have been developed to synthesize CFH- and phosphinoyl-containing quinolines from -isocyanyl α-trifluoromethylstyrenes. The reaction proceeded under redox-neutral conditions and allowed the construction of a highly attractive quinoline ring system, with the simultaneous formation of the CFH group and introduction of various phosphinoyl groups in a single transformation, showing operational simplicity, a wide substrate scope, good tolerance for functional groups, and remarkable atom-/stepeconomy. Mechanistic studies indicated that the reaction is likely to involve the participation of P-centered radicals and key carbanion intermediates.

Dioxygen (O) is a potent oxidant used by aerobic organisms for energy transduction and critical biosynthetic processes. Numerous metalloenzymes harness O to mediate C-H bond hydroxylation reactions, but most commonly feature iron or copper ions in their active site cofactors. In contrast, many manganese-activated enzymes─such as glutamine synthetase and isocitrate lyase─perform redox neutral chemical transformations and very few are known to activate O or C-H bonds.

A novel method is reported to synthesize various pyrazolones through transition-metal-free and redox-neutral 1°, 2°, or 3° C(sp)-H carbonylative cyclization using 1 atm of CO as a green carbonyl source, featuring good functional group tolerance, a broad substrate scope, facile scalability, and easy product transformation. The utility of this method could be demonstrated by the applications in preparing useful synthetic intermediates and bioactive compounds.

Article Synopsis
  • The article discusses a new method for synthesizing α-heteroatom-substituted secondary amides, which are important in chemistry but hard to make using traditional techniques.
  • It utilizes a unique umpolung procedure that allows for the functionalization of carbonyl groups at the α-position without needing external oxidants, simplifying the synthesis.
  • The process has strong theoretical backing, showing that a combination of Mg and DIPEA plays a crucial role in forming intermediates, making this protocol the first reliable method for creating these specific amides.
