Description

technical field

[0001] The invention belongs to the technical field of photocatalytic materials, and in particular relates to a metal-organic framework material for visible light-catalyzed bifunctionalization of styrene and its preparation method and application. Background technique

[0002] In terms of catalysis, the ecologically sustainable synthesis of 1,3-oxathiolane-2-imino derivatives is very attractive both academically and industrially, as they are very valuable intermediates in organic synthesis , and has been used as a core structure for the development of anticancer drugs. In the reported literature, the difunctionalization of styrene via visible light-photoredox catalysis is an effective strategy, which utilizes the cheapest visible light and can utilize oxygen in the air to form free radicals in situ as oxidants. Facilitates the catalytic cycle.
