Embodiment 1

[0056] The preparation method of compound I-1 is as follows:

[0057]

[0058] (1) Preparation of intermediate 3-1

[0059] Add 100ml of tert-amyl alcohol into a 250ml three-neck flask, then cut 4g of sodium into sodium particles and add it, and then add ferric chloride with a catalytic amount of 20-40mg as a catalyst. Heat to 100~105°C, react for 2~3h. Cool down to 50-60°C, add 68.6mmol of compound 2-1, then heat to 100-105°C, add 8ml of diisopropyl succinate compound 1 and 40ml of tert-amyl alcohol into the three-necked flask with a constant pressure dropping funnel , 3 ~ 5s / d, 2-3h drop. Finally, react for another 4 hours, stop the reaction, pour the reaction product into a beaker, add 100ml of methanol to dilute, then add acetic acid to adjust the pH to 7, filter with suction, wash the filter cake with methanol, take the filter cake, heat and dry it, and then use N, N-dimethylformamide was dissolved in heat, cooled and suction filtered, the filter cake was washed wit...

Abstract

The invention discloses a fluorine-containing diketopyrrolopyrrole quaternary ammonium salt compound, the structure of which is shown in formula I: R 1 for F, CH 2 F. CHF 2 、CF 3 , OCH 2 F. OCHF 2 、OCF 3 、SCH 2 F. SCHF 2 、SCF 3 、CF 2 (CF 2 ) n CF 3 A kind of, n is an integer from 0 to 10; X is F, Cl, Br, I. The present invention selects diisopropyl succinate and differently substituted benzonitriles as raw materials to prepare fluorine-containing pyrrolopyrrole diketone quaternary ammonium salt compounds, which can be used as electroplating leveling agents.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a fluorine-containing diketopyrrolopyrrole quaternary ammonium salt compound and a preparation method and application thereof. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. Electroplating technology is widely used. There are electroplating products around our lives, such as: necklaces, rings, clocks, belt buckles and other accessories, pens, staplers, pencil cases, scissors and other stationery, air conditioners, refrigerato...
