Highly effective CS2 conversion with aziridines catalyzed by novel [Dy24] nano-cages in MOFs under mild conditions

Abstract

Converting CS₂ into high-value products is an emerging and effective strategy for disposing of CS₂, which can avoid generating various toxic pollutants caused by the traditional method of incinerating CS₂. However, there are great challenges involved in searching for novel catalysts to obtain highly effective CS₂ conversion with aziridines under mild conditions. Herein, a novel MOF (1) assembled from [Dy₂₄] nano-cages was constructed, and showed excellent catalytic activity for CS₂ conversion with aziridines under mild conditions, along with the recorded turnover frequency (TOF) value of 51.1 h⁻¹. Catalyst 1 could be reused at least five times without obvious loss of catalytic performance, and was applied to a gram-scale experiment, which showed a promising practical application for CS₂ disposal. In addition, the corresponding production can be simply recrystallized to obtain highly purified intermediates for use in organic synthesis and medicinal chemistry. Importantly, 1 represents the first example of a MOF-based catalyst for CS₂ conversion with aziridines.
