A sulfonate-functionalized water-soluble Ni( ii )–NHC catalyst is utilized for the oxidative deamination of benzyl amines, wherein water acts as a formal oxidant to give an aldehyde, which then converted useful products.
Abstract A terminal [Ni II −OH] complex 1 , supported by triflamide‐functionalized NHC ligands, showed divergent reactivity for the reaction of sulfone with alcohol, contingent on base concentration, temperature, and time. Julia‐type olefination alcohols sulfones was achieved using one equiv. base, whereas lowering loading to 0.5 afforded α ‐alkylated sulfones. Besides excellent substrate scope selectivity, biologically active stilbene derivatives DMU‐212, pinosylvin, resveratrol,...
A pyridine and morpholine-functionalized dicopper(I,I)-NHC complex (1) features both terminal bridging coordination modes of NHC within the same molecule, catalyzes dual ortho-C-H functionalization diaryl amines for hydroarylation alkynes. bimetallic construct in catalyst 1 allows sequential activation bonds two aryl units to furnish a wide variety 9,10-dihydroacridine derivatives without explicit use directing group.
Abstract The catalytic activity of a Ru complex 1 , bearing fused π‐conjugated imidazo[1,2– ][1,8]naphthyridine‐based mesoionic carbene (MIC) ligand, is examined for the oxidation primary amines. Complex affords nitrile or imine depending on nature terminal oxidants and solvents used in reactions. Primary amines are converted to nitriles using NaIO 4 EtOAc/H 2 O mixture, whereas imines obtained under balloon pressure toluene. A variety accessed with high yields selectivity. set control...
