Title:
PREPARATION METHOD FOR CONJUGATED DIENE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2019/052236
Kind Code:
A1
Abstract:
The present invention pertains to the field of fine chemicals and related chemical technologies and provides a preparation method for a butadiene derivative. Phenylacetylene and derivatives thereof are used as raw materials and react in an anhydrous organic solvent under the action of a metal catalyst and an additive, to be transformed into a 2,3-disubstituted-1,3-butadiene compound. The present invention has the beneficial effects of simple operation, mild preparation conditions, environmental friendliness, industrialization potential, and production of a higher yield butadiene compound. The butadiene compound synthesized by the method can further be functionalized to obtain various types of compounds for subsequent application in the research and development of natural products, functional materials, and fine chemicals.
