Embodiment Construction

[0022] Method steps of the present invention are:

[0023] 1. Synthesis of m-bromophenetole

[0024] Add the sodium hydroxide of 30ml water and 0.15mol in the 100ml three-neck flask that electric stirrer, reflux condenser and dropping funnel are housed, then add m-bromophenol and tetrabutylammonium iodide, and the addition is, n( m-bromophenol): n (sodium hydroxide) = 2: 3 ~ 1: 1, n (tetrabutylammonium iodide): n (sodium hydroxide) = 0.04: 1 ~ 0.06: 1, at 60 ~ 80 ° C Add 5-10 ml of bromoethane under stirring; after reacting for 2-2.5 hours, cool, separate the organic phase, and extract the water phase with ether; combine the organic phases and wash with 10% NaOH solution, then wash with water until neutral, and use Dry with anhydrous sodium sulfate; evaporate the solvent, then distill under reduced pressure, collect the fraction at 130-135°C to obtain colorless liquid m-bromophenetole;

[0025] The reaction equation is:

[0026]

Abstract

The invention provides a method for synthesizing tri(m-ethoxyphenyl)bismuthine, relates to a method for synthesizing triphenylbismuth derivatives, in particular to a method for synthesizing tri(m-ethoxyphenyl)bismuthine. The method for synthesizing tri(m-ethoxyphenyl)bismuthine has the advantages of simpleness in operation, high yield and favorability of industrialized production. The method comprises the steps of: synthesizing m-bromophenetole; synthesizing m-ethoxyphenyl magnesium bromide; and synthesizing the tri(m-ethoxyphenyl)bismuthine.

Description

Technical field: [0001] The invention relates to a synthesis method of triphenylbismuth derivatives, more specifically, to a synthesis method of tri-ethoxyphenylbismuth. Background technique: [0002] Triphenylbismuth series compounds are one of the raw materials in composite solid propellants for aerospace rockets and missiles. They are often used as catalysts for composite solid propellants, and they are also widely cited and applied in the process of drug synthesis and chemical material preparation. [0003] Bismuth triethoxyphenyl, chemical formula C 24 h 27 BiO 3 , the structural formula is shown in the figure below. [0004] [0005] bismuth triethoxyphenyl [0006] At this stage, the synthesis of bismuth tri-ethoxyphenyl is still in the experimental stage, and no industrial production has been carried out. Invention content: [0007] The present invention aims at the above problems and provides a synthesis method of tri-methoxyphenyl bismuth which is simple ...
