Description
Technical field:
The present invention relates to technical field of organic synthesis, and in particular to a kind of preparation method of 2 nitro biphenyl.
Background technology:
2 nitro biphenyl as function dough biphenyl compound, in agricultural chemicals and medical synthesis field, with important
Value.The analog of presently disclosed 2 nitro biphenyl, generally passes through precious metal palladium, cobalt, Huo Zhetong using boric acid as substrate
Cross reaction under high pressure to prepare, such as:
1st, patent CN201410692141, using palladium diacetate as catalyst, use to chlorophenylboronic acid and 2- nitrophenyl hydrazines for
Raw material, is prepared for 2 nitro biphenyl class compound.
2nd, patent CN201410785170, using palladium as catalyst, the nitre replaced using 3,4,5- trifluoro phenyl boric acids and ortho position
Base benzene is raw material, is prepared for 2 nitro biphenyl class compound.
3rd, document [Catalysis Communications, 2016, Vol.82, p24-28], [Journal of the
American Chemical Society,2016,Vol.138,p6392-5]、[Advanced Synthesis and
Catlysis, 2010, Vol.352, p3089-97], deliver and be coupled by suzuki, by 2- chloronitrobenzenes and the benzene of substitution
Boric acid is under noble metal catalyst, the method that coupling prepares 2 nitro biphenyl class compound.
The content of the invention:
The technical problems to be solved by the invention are that providing one kind prepares that cost is low, isolate and purify simple to operate and product
The preparation method of the high 2 nitro biphenyl of purity.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of preparation method of 2 nitro biphenyl, reaction raw materials, copper are used as using 2- nitrobenzene NITRODIAZONIUM FLUOROBORATE and chlorobenzene
As catalyst, under nitrogen protection backflow ullmann reaction occurs for powder, and reaction is filtered to remove insoluble matter after terminating, and through decompression
Product 2 nitro biphenyl is made in distillation.
The mol ratio of the 2- nitrobenzene NITRODIAZONIUM FLUOROBORATE, chlorobenzene and copper powder is 1:5-10:0.03-0.05.
The reaction time is 5-8h.
The copper powder mesh number is 100-200 mesh.
The beneficial effects of the invention are as follows:
(1) using excessive chlorobenzene simultaneously as reaction raw materials and reaction dissolvent, without adding other reaction dissolvents, reduce
The independent reclaimer operation of reaction dissolvent, reaction terminate after only need vacuum distillation chlorobenzene can using unreacted chlorobenzene and as react
The chlorobenzene of solvent is reclaimed in the lump, it is to avoid the waste of raw material and directly pollution of the discharge to environment;
(2) using copper powder as catalyst, 2 nitro biphenyl is prepared through ullmann reaction, different from through suzuki coupling reactions
The method for preparing 2 nitro biphenyl, it is to avoid the use of palladium class noble metal catalyst, is urged using copper powder cheap and easy to get as reaction
Agent, significantly reduces the use cost of catalyst, so that suitable for industrialized production;
(3) more than 98% can be reached by 2 nitro biphenyl purity made from herein described synthetic method, and yield reaches
To more than 75%, post-processing operation is simplified on the basis of low preparation cost, it is ensured that product purity.
