An immobilized iridium complex photocatalyst Ir(ppy)2(PDVB-py) was synthesized by immobilization of the iridium complex onto the nanoporous vinylpyridine-divinylbenzene copolymer (PDVB-py). Its application for the synthesis of amides, nitriles, and anhydrides was reported via reactions under the action of the visible-light-driven in situ generated Vilsmeier-Haack reagent from CBr4 in DMF. The results showed that this heterogeneous photocatalyst has extremely high activity and excellent stability to be recycled five times.

Paragraph 0038-0040, (2018/07/30)
The invention belongs to the technical field of ketoxime and specifically relates to a preparation method of ketoxime. The preparation method comprises the following steps: (1) sufficiently mixing ketone and hydroxylamine hydrochloride, adding absolute ethyl alcohol, and stirring till total dissolution to obtain mixed liquid 1; (2) adding imidazolyl anion functionalized ionic liquid into the mixedliquid 1, and heating till ethanol reflux, wherein reaction liquid is obtained after the reaction; (3) removing ethanol in the reaction liquid, adding deionized water and stirring to separate out solid, and performing suction filtration and washing to obtain white solid ketoxime. According to the preparation method provided by the invention, by taking the imidazolyl anion functionalized ionic liquid as a catalyst, a reaction between ketone and hydroxylamine hydrochloride can be efficiently catalyzed, and the preparation method has the advantages of mild reaction conditions, high product yieldand purity and the like.
