Abstract
The invention is a substituted cis-1, 2-ethylene dicyanide and its synthetic method: (1) synthesizing substituted trans-1, 2-ethylene dihalide and substituted cis-1, 2-ethylene dihalide; (2) synthesizing substituted trans-1, 2-ethylene dicyanide and substituted cis-1, 2-ethylene dicyanide; (3) converting substituted trans-1, 2-ethylene dicyanide to the optical isomer of substituted cis-1, 2-ethylene dicyanide; it broadens the modifiability of tetraazaporphyrin complex, and increases the solubility of its metal complex; the synthetic method and conditions are moderate, have no special requirements for the reacting system, the raw materials have low toxicity and the total productivity is high.
Description
Technical field
The present invention relates to a kind of replacement cis 1,2-two acrylonitriles and synthetic method thereof, the particularly cis 1 that replaces about alkyl, aryl, 2-dicyan ethylene product and synthetic method.Method of the present invention can be widely used in the cis 1 that alkyl, aryl replace, 2-two acrylonitriles synthetic, and its compound and derivative thereof are one of synthetic important intermediate that replaces tetraazatetradecane porphyrin class title complex.
Background technology
Tetraazatetradecane porphyrin and title complex thereof make it all have very wide application prospect in fields such as biology, bionics, materialogy, pharmacology, electrochemistry, optical physics chemistry as anticancer photosensitizer, optical storage media, nonlinear optical material, the quick material of air humidity or the like because it has special macrocyclic structure and excellent physics, chemical property.Do not replace the poorly soluble of tetraazatetradecane porphyrin and title complex thereof owing to have, the research and the application of a lot of character are restricted, thereby improve the solvability of tetraazatetradecane porphyrin title complex, and the high-efficiency synthesis method of seeking solubility tetraazatetradecane porphyrin title complex becomes the major issue that needs to be resolved hurrily at present.Cis-1,2-two acrylonitriles (also being Maleic nitrile) and trans-1,2-two acrylonitriles (also being flumaronitrile) and derivative thereof are one of intermediates of synthetic this compounds necessity, but trans-isomer(ide) trans-1,2-two acrylonitriles and derivative thereof are owing to structural reason, synthetic yield is far away from cis-isomeride, thereby is domestic and international scientist's research focus to the synthetic and performance study of Maleic nitrile (cis-1,2-two acrylonitriles) and their various derivatives always.Once reported the synthetic cis 1 that replaces of several differences in the document, the method of 2-two acrylonitriles: (1) document Zh.Org.Khim.1992,28 (10): 2149-2155 and Zh.Org.Khim.1979,15 (5): the method for 1076-1082 be with one or the dichloro Maleic nitrile in active chlorine atom carry out the synthetic target Maleic nitrile intermediate of nucleophilic substitution with other substituting group (as alkoxyl group, alkylthio etc.), the raw material one of this method or dichloro Maleic nitrile normally with succinonitrile or with phosphorus pentachloride or with chlorine reaction synthetic.The main drawback of this method is that raw material is expensive, phosphorus pentachloride or chlorine are the materials of strong moisture absorption and severe toxicity, and in the nucleophilic substitution process, there are some unsettled intermediates to produce, so the control to conversion unit and experiment condition requires also very high (such as waterless operation, temperature control), it is mainly used in the tetraazatetradecane porphyrin title complex of synthetic alkoxyl group, aryloxy replacement simultaneously.(2) document Inorg.Synth.1967,10:8-26 and Inorg.Chem.1980,19:383-385 is with a halohydrocarbon or dihalo hydrocarbon and the effect of Maleic nitrile disodium salt, obtain the Maleic nitrile intermediate that the dialkyl group of cis replaces, can react with dithiocarbonic anhydride by sodium cyanide as the Maleic nitrile disodium salt of raw material and obtain.The starting raw material sodium cyanide of this method and dithiocarbonic anhydride all are highly toxic substances, easily operator and environment are damaged, and in addition, this method can only be synthesized the tetraazatetradecane porphyrin title complex that is connected with eight alkylthios.Document Zh.Obshch.Khim.1977,47 (9): 2143-2148 once reported with cis-1,2-two bromo-tertiary butyl ethene are raw material, prepare cis-1 through cyaniding, the process of 2-dicyan-tertiary butyl ethene, and document Synthesis.1991,686-688 reported once that to replace alkynes be raw material, through bromination, reaction such as cyaniding and photoisomerization, preparation alkyl or aryl Maleic nitrile intermediate, the main drawback of these two kinds of methods are that per step reaction all needs pure substance, especially replace trans-1,2-sym-dibromoethane and replacement cis-1,2-sym-dibromoethane similar performance, separation difficulty, the trans-1 that separates, the 2-sym-dibromoethane is not used to next step reaction, thereby the synthetic overall yield is very low, and cost increases.
Summary of the invention
Purpose of the present invention is exactly the problem and shortage that exists in the above-mentioned prior art, research and design provides a kind of replacement cis 1,2-two acrylonitriles and synthetic method thereof, reach improve the sintetics overall yield, reduce production costs, raw material low toxicity and utilization ratio height, reaction conditions gentleness, purpose that reaction system is had no special requirements, alleviates and avoids operation producers and environment are damaged.
Basic design of the present invention is, replaces cis 1, and the general formula of molecular structure of 2-two acrylonitriles is as follows:
C in the structural formula and N represent carbon and nitrogen respectively; R and R ' represent hydrogen atom, methyl, ethyl, propyl group, sec.-propyl, butyl, isobutyl-, the tertiary butyl and other straight chain, side chain and cyclic alkyl (C
1-20Individual carbon atom), aromatic base, heterocyclic radical; Above-mentioned replacement cis 1, two itrile groups of 2-two acrylonitriles are active groups that cyclization forms metal complexes.Above-mentioned replacement cis 1, the R of 2-two acrylonitriles and R ' substituting group have regulating effect to the metal complexes that forms in the solubleness of general organic solvent, are the important intermediate of preparation solubility tetraazatetradecane porphyrin title complex.
Replace cis 1,2-two acrylonitrile synthetic methods are as follows:
(1) replaces trans-1,2-acetylenedihalide and replace cis-1,2-acetylenedihalide synthetic
In reaction flask, add organic solvent 1 and replace alkynes, slowly splash in the above-mentioned solution with the mixed solution of dropping funnel with halogen and organic solvent 1, the mol ratio that replaces alkynes and halogen is 1: (1-1.4), and after dripping off, normal temperature continued stirring reaction 1-20 hour, reaction solution obtains product and replaces trans-1 after washing, boiling off solvent, 2-acetylenedihalide and replacement cis-1,2-acetylenedihalide mixture, the two mixture is directly used in the next step without separation, and also available column chromatography is further purified.
