Preparation method of water-soluble vitamin E participated conjugated diyne compound

The water-soluble vitamin E participates in the green preparation method of the conjugated diyne compound, the water serves as a reaction solvent, the use amount of the organic solvent is reduced, and zero emission of the solvent is realized. The excellent physicochemical properties of water are fully utilized, the reaction conditions are mild and efficient, the surfactant TPGS - 750 - M can be recycled through treatment, and the principle of environmental friendliness is completely met. The reaction substrate is wide in applicability, can catalyze the aryl alkyne, can catalyze the aliphatic hydrocarbon, and provides a simple and environment-friendly preparation method for the synthesis of the conjugated diyne. The copper catalyst which is more suitable for the reaction and reaction medium of the invention is screened out, and the yield is greatly improved.
