Ligand-Controlled Regiodivergence for Catalytic Stereoselective Semireduction of Allenamides

supporting information, (2021/12/02)
Ligand-controlled regiodivergence has been developed for catalytic semireduction of allenamides with excellent chemo- and stereocontrol. This system also provides an example of catalytic regiodivergent semireduction of allenes for the first time. The divergence of the semireduction is enabled by ligand switch with the same palladium pre-catalyst under operationally simple and mild conditions. Monodentate ligand XPhos exclusively promotes selective 1,2-semireduction to afford allylic amides, while bidentate ligand BINAP completely switched the regioselectivity to 2,3-semireduction, producing (E)-enamide derivatives.

In transition-metal-mediated catalysis, designing new, well defined coordination architectures and subjecting them to catalysis testing under the same reaction conditions is a necessary tool for gaining an improved understanding of desirable active site geometries and characteristics. In this work, three ligands varying in chelation and charge characters (1= tridentate, dianionic N^N^N;2= bidentate, dianionic N^N;3= bidentate, neutral N^O) were synthesized and introduced as organic backbones around cobalt(ii) centres. Four multinuclear coordination assemblies incorporating various group I metal ions (i.e., (Na-Co1-i)2, (Na-Co1-e)2, (K-Co1-e)2and (Cs-Co1-e)2) and two mononuclear complexes (i.e.,Co2andCo3) were isolated, structurally characterized and studied as phenoxazinone synthase models. X-ray data and Continuous Shape Measure (CShM) calculations described unusual vacant trigonal bipyramidal geometries for (Na-Co1-i)2, (Na-Co1-e)2andCo3, trigonal bipyramids for (K-Co1-e)2and (Cs-Co1-e)2, and a tetrahedron forCo2. According to mass spectrometry data, the four multinuclear (MI-Co1-solvate)2complexes of ligand1easily dissociate in solution to yield the corresponding ions including a common mononuclearCo1unit. Testing as models in the oxidative coupling ofo-aminophenol revealed that an increasing chelate character of the organic ligand backbone produces an undesirable catalyst activity reduction. Furthermore, the similarity in coupling efficiencies observed among complexes (Na-Co1-i)2, (Na-Co1-e)2, (K-Co1-e)2and (Cs-Co1-e)2proves that the presence of varying group I metal ions contributed no catalytic effects to the coupling efficiencies and that theCo1species, which is generated by dissociation in solution, is the only active species responsible for the observed biomimetic behaviours. Therefore, the combination of anionic chelate ligands with easily detachable, neutral co-ligands (e.g., water or pyridine) around a cobalt(ii) centre could be recommended for the generation of a successful catalyst material, rather than the combination of a neutral chelate ligand with counter-anionic monodentate co-ligands like halides.
