Method for synthesizing trans-olefin compound

The invention discloses a trans-olefin compound synthesis method, which comprises: carrying out a heating reaction on an alkyne compound represented by a general formula (I), a reducing agent and a solvent to obtain a trans-olefin compound represented by a general formula (II), wherein the synthesis route is as follows: R1 and R2 are independently selected from hydrogen, alkyl, cycloalkyl or aryl;wherein the reducing agent is a sulfur-containing compound and is selected from at least one of thioacetamide, N,N-dimethyl dithiocarbamate dimethyl ammonium salt, dimethyl amino sodium dithioformatedihydrate, potassium ethyl xanthate and potassium isopropyl xanthate. According to the method, a cheap, efficient and safe reducing agent is utilized to realize high-selectivity reduction of alkyne to prepare trans-olefin under the condition of no transition metal catalysis, so that the method is simple and easy to implement, wide in substrate application range and easy to realize industrialization.

Preparation method of palladium catalyzed 1,2-trans diaryl alkene

The invention discloses a preparation method of palladium catalyzed 1,2-trans diaryl alkene. The method comprises the following steps that under the effects of catalysts, cocatalysts and alkali, arylacrylic acid and aromatic esters p-toluene sulfonate take decarboxylation coupling reaction in an organic solvent; after the reaction is finished, the 1,2-trans diaryl alkene is obtained through posttreatment. The method has the advantages that through C-O bond fracture, the operation is simple; a stable palladium catalyst with low cost is used; the substrate applicability is high; the harsh reaction conditions and the addition of strong alkali are not needed; the trans 1,2-diaryl alkene can be generated at high selectivity.
