Embodiment 1

[0017] Add ferric chloride and ionic liquid 1-ethyl-3-methylimidazolium bromide into the reaction kettle at a mass ratio of 1:15, heat up, and control the temperature at 65°C. After completely dissolving, add 2g of cinnamyl alcohol, Stir at ℃ for another 1-5 hours until the reaction is complete. The reaction mixture was cooled to room temperature. The organic layer was separated, filtered through a funnel, and washed to obtain the desired product as a white solid.

Embodiment 2

[0019] Add ferric chloride and ionic liquid 1-ethyl-3-methylimidazolium chloride into the reaction kettle at a mass ratio of 1:10, heat up, and control the temperature at 70°C. After completely dissolving, add 3g of cinnamic acid, Stir at ℃ for another 1-5 hours until the reaction is complete. The reaction mixture was cooled to room temperature. The organic layer was separated, filtered through a funnel, and washed to obtain the desired product as a white solid.

Embodiment 3

[0021] Add ferric chloride and ionic liquid 1-propyl-3-methylimidazolium bromide into the reaction kettle at a mass ratio of 1:20, heat up and control the temperature at 75°C, after completely dissolving, add 2g of p-methoxycinnamon acid, and stirred at 75°C for another 1-5 hours until the reaction was complete. The reaction mixture was cooled to room temperature. The organic layer was separated, filtered with a funnel, and washed to obtain the desired product as a black-purple solid.

Abstract

The invention relates to a method for preparing ferruginous cinnamon series metal organic matters in an ionic liquid, comprising the following steps: using mononuclear nitrogenous cation comprising alkyl imidazole, alkyl pyridine, etc. and a liquid ionic liquid comprising halogen anions and amino acid anions at room temperature as a solvent, and using ferric trichloride, cinnamyl alcohol and a series of compounds which are similar in structure to react in the solvent of the ionic liquid to prepare the novel metal organic matters. Compared with other methods, ferric trichloride used in the method has the characteristics of low price, low toxicity, relatively environmental-friendly property, and good stability of the prepared cinnamon series metal organic matters. The solvent has the characteristics of structure adjustability and repeatedly usable property, and is beneficial for environmental protection. The prepared cinnamon series metal organic matters have novelty and have a good application prospect.

Description

technical field [0001] The invention relates to a method for preparing iron-containing cinnamon series metal organic compounds in ionic liquid, in particular to a method using ionic liquid as a solvent and ferric chloride and cinnamon series compounds as reactants. Through the reaction, a series of iron-containing solid metal organic compounds with various structures can be economically, conveniently and environmentally friendly obtained. Background technique [0002] Iron, one of the most abundant metals on Earth, has been increasingly used in modern catalysis to discover its unique and novel reactions to carbon-carbon and carbon-heteroatom bond formation. The transformation of carbon-hydrogen (C-H) bond is one of the most important and fundamental research contents in organic chemistry. The formation of new functional groups by directly activating and inducing C-H bonds is undoubtedly an attractive and challenging reaction strategy, which embodies the characteristics of a...
