Description
Technical field
The invention belongs to organic synthesis intermediate, medicine, agricultural chemicals and liquid crystal material field, be specifically related to a kind of 1,4-diaryl-1, the preparation method of 3-diacetylene.
Background technology
1,3-diacetylene compound is the very important organic compound of a class, and they are widely used in fields such as organic synthesis intermediate, medicine, agricultural chemicals and liquid crystal material.As conjugation linker important in the organic synthesis, 1,3-diacetylene compound is known as the omnipotent module that makes up molecule, can be used in macromolecular compound such as annulene synthetic, also can be used for synthetic organometallics and derivatives of porphyrin etc. (Li, C.Langmuir 2007,23,6754).1,3-diacetylene compound also is the structural unit (Shi Shun, A.L.K.Angew.Chem.Int.Ed.2006,45,1034) of natural product, antifungal drug.Because it has natural photosensitivity; 1; the 3-diacetylene is used to photo-activation pesticide; to the Culex quinquefasciatus instar larvae have stronger photoactivation poisoning effect (Wan Shuqing. insect journal .2000; 43,264), to the growth of barnyard grass grass roots and stem have the photoactivation restraining effect (Wan Shuqing. plant protection journal .2004; 31,299).Based on 1,3-diacetylene compound has the photoelectron performance of regulating molecule, the effect of induced fluorescence enhanced, thereby they also are used as the liquid crystal material use.As seen 1,3-diacetylene compound has crucial effect in fields such as organic synthesis, medicine, agricultural chemicals and liquid crystal material.
Bibliographical information is arranged, institute of the present invention synthetic 1,4-diaryl-1,3-diacetylene compounds be a kind of novel, efficient, low toxicity, low residue photo-activation pesticide (Wu Renhai. the journal .2008 of Agricultural University Of South China, 29,44), under the artificial light irradiation of daylight or specific wavelength, show strong insecticidal activity, thereby this insecticides is expected to become the surrogate of traditional chemical sterilant.Experimental results show that, in 1 of 100 μ g/mL mass concentrations, 4-phenylbenzene-1,3-diacetylene and 1,4-two (3, the 4-methylene-dioxy) phenyl-1, under the effect of 3-diacetylene, the mortality ratio of Aedes albopictus is 100%, and visible 1,4-diaryl-1,3-diacetylene compounds has stronger photoactivation poisoning effect to Aedes albopictus.
Usually preparation 1,4-diaryl-1, the method for 3-diacetylene is in the presence of transition metal copper or palladium, under the fellowship effect of containing n-donor ligand, terminal alkyne takes place to obtain (Adimurthy, S.J.Org.Chem.2009,74,5648 from linked reaction; Yin, W.Org.Lett.2009,11,709).Palladium catalyst cost an arm and a leg and toxicity bigger, very sensitivity and price are not low to air for containing n-donor ligand.
β, beta-2-dibrom vinyl compound are the multi-functional organic synthesis intermediates of a class, are widely used in the starting raw material of organic synthesis.People such as Yan have reported in the presence of potassium tert.-butoxide, in toluene solvant, β, beta-2-dibrom ethene takes place to obtain 1 of higher yields from linked reaction, 4-two replaces-1,3-diacetylene compound, but reaction conditions is gentle inadequately, need carry out (Yan under 120 ℃ of temperature, J.Synth.Commun, 2005,35,2333).
People such as Hitomi have reported in the presence of cuprous iodide and potassiumiodide are common, β, beta-2-dibrom vinylbenzene is by obtaining 1 from linked reaction, 4-phenylbenzene-1, the synthetic method of 3-diacetylene, the consumption of cuprous iodide is not a catalytic amount for the chemistry amount in this method, thereby consumption is big, cost height (Suzuki, H.Synthesis., 1988,236).
People such as Regis are with β, beta-2-dibrom vinylbenzene is raw material, with the nickelous acetate is catalyzer, does in the presence of the part preparation 1 at sodium hydride and two pyridines, 4-phenylbenzene-1,3-diacetylene, but big (Regis, V.Tetrahedron Lett.1986 of the toxicity of catalyzer and part in this method, 27,3517).
Therefore, the present invention is with β, and the beta-2-dibrom aromatic ethylene is a raw material, is catalyzer with CuI, does not need to add any part, preparation 1,4-diaryl-1,3-diacetylene compound.This method has advantages such as raw material is easy to get, with low cost, simple to operate, reaction conditions gentleness, is easy to industrialization, has broad application prospects.
