This work presents preparation of a surface modified magnetically tuned solid acid where thiol groups were grafted on magnetic halloysite, followed by oxidation of thiol groups to sulfonic acid groups. The physicochemical properties of the catalyst were a

We contributed a new benzimidate chemistry through moisture-insensitive NiII/NiII-FeIII combo-catalysis for a simultaneous 2-3 bond-forming gem-diamidation and amidoindolyzation cascade reaction to construct symmetrical an

Several novel pyridine-oxadiazole iridium complexes were synthesized and characterized through X-ray crystallography. The designed iridium complexes revealed surprisingly high catalytic activity in C–N bondformation of amides and benzyl alcohols with the assistance of non-coordinating anions. In an attempt to achieve borrowing hydrogen reactions of amides with benzyl alcohols, N,N'-(phenylmethylene)dibenzamide products were unexpectedly isolated under non-coordinating anion conditions, whereas N-benzylbenzamide products were achieved in the absence of non-coordinating anions. The mechanism explorations excluded the possibility of “silver effect” (silver-assisted or bimetallic catalysis) and revealed that the reactivity of iridium catalyst was varied by non-coordinating anions. This work provided a convenient and useful methodology that allowed the iridium complex to be a chemoselective catalyst and demonstrated the first example of non-coordinating-anion-tuned selective C–N bond formation
