| 英文摘要 | The tandem reaction is a growing field to yield important advances toward green and sustainable chemistry. herein, we report a bifunctional manganese oxide catalyst with an interface binding redox phase (alpha-mno2) and a basic phase (naxmno2). the molar ratio of naoh/mn plays a great role in the formation of alpha-mno2/naxmno2. the sodium cation is essential for the formation of a basic naxmno2 phase while the potassium cation promotes the formation of a redox-active alpha-mno2 phase. the interface structure of alpha-mno2/naxmno2 geometrically favors the ammoxidation-pinner tandem reaction to synthesize imidates in a 58-96% yield from aldehydes. thus a phase collaborative effect is observed. in the ammoxidation process, the redox cycle of mn-iv/mn-iii is involved and the lattice oxygen in the alpha-mno2 phase acts as an active oxygen species. the o-h in methanol is activated and dissociated on the basic sites of naxmno2 to the adsorbed methoxyl species to facilitate the pinner synthesis. this approach bypasses the conventional synthesis of imidates, which suffer from harsh reaction conditions and the requirement for multiple steps. |
