Abstract

The invention discloses an organic compound, which is characterized in that: the compound has the structure of a formula (I): RAn (I); A has a nitrone ligand with the structure of a formula (II); n is 1 or 2; R is selected from one of the following aryl groups: phenyl group or naphthyl group, and R is substituted by one or more of the following groups: hydrogen, nitro group, trifluoromethyl group, halogen, methyl group, methoxy group, hydroxy group, phenyl group, phenolic group and isopropyl group. The compound can be synthesized into a series of catalysts with high catalytic activity and a high turnover rate, various easy-obtained, economic substituted Alpha-phenethyl alcohol compound and phenethyl alcohol compound can be catalyzed under mild conditions to react to prepare various alcohol compounds, the reaction can obtain a high reaction yield in a short reaction time, meanwhile, almost no byproducts are produced, and therefore the reaction is environment-friendly green catalytic reaction and atomic economic catalytic reaction.

Description

technical field The invention belongs to the technical field of organic chemistry synthesis, and specifically relates to a novel nitrone ligand, an organometallic iridium catalyst and a preparation method thereof, and the application of the organometallic iridium catalyst in the synthesis of organic compounds to form carbon-carbon bonds Background technique Carbon-hydrogen bond activation is not only a challenge at the frontiers of organic chemistry science, but will also be at the heart of a new generation of material transformations. However, due to the similar electronegativity of carbon atoms and hydrogen atoms, the carbon-hydrogen bond presents the basic structural characteristics of relatively stable and low polarity. A chemical transformation takes place, so the first problem encountered in this regard is its low reactivity. For relatively complex organic compounds, there are many different carbon-hydrogen bonds in the same molecule, so how can we realize the transfo...
