Cu-Pd dissimilar metal cluster and preparation method thereof

The invention discloses a Cu-Pd dissimilar metal cluster and a preparation method thereof, and belongs to the technical field of metal cluster materials. According to the principle of soft and hard acid and base, Cu and Pd with different coordination are selected, under the action of dppy and a reducing agent, alkene dianions with a pi bond being mu4 coordination in alkynyl of an alkyne compound are activated, and the Cu-Pd dissimilar metal cluster is synthesized through reduction with a one-pot method at normal temperature. The Cu-Pd dissimilar metal cluster can be used for activating terminal alkyne and internal alkyne, Cu and Pd in the metal cluster can synergistically activate a pi bond to form mu4 coordinated enedianion, and compared with a traditional Cu-Pd dissimilar metal cluster for alkyne sigma bond activation, the Cu-Pd dissimilar metal cluster can achieve activation of an alkyne compound pi bond. 本发明公开了一种Cu-Pd异金属团簇及其制备方法，属于金属团簇材料技术领域。根据软硬酸碱原理，选择配位不同的Cu和Pd，在dppy和还原剂的作用下，活化炔类化合物炔基中π键为μ4配位的烯二负离子，常温下经
