Gold-{2-(9-anthracene phenyl)dicyclohexylphosphine}-acetonitrile complex synthesis and application thereof

The invention relates to a gold metal complex which is [Au{dicyclohexyl-[2-(9-anthracene)phenyl]phosphine}-NCCH3](SbF6), and the gold metal complex can be conveniently synthesized. The ligand can be synthesized in a simple mode, and large scale industrial production can be realized through stable existence of the ligand in air under normal temperature. The gold complex is capable of catalyzing a cycloaddition reaction of 1,6-eneyne, and has good reaction activity. The catalyst has the advantage of less catalyst amount of a traditional metal complex, and overcomes the disadvantage of expensive cost of noble metal catalysts such as Pd and Pt. The reaction is carried out in a dichloromethane system, the catalyst amount is less, reaction condition is mild, reaction time is short, and post-treatment is convenient. The catalyst has important application in the cycloaddition reaction, and has large application prospect in industrial production.
