We present a direct cross-coupling reaction between arylaluminum compounds (ArAlMe2·LiCl) and organic halides RX (R=aryl, alkenyl, alkynyl; X=I, Br, and Cl) without any external catalyst. The reaction takes place smoothly, simply upon heating, thereby enabling the efficient and chemo-/stereoselective formation of biaryl, alkene, and alkyne coupling products with broad functional group compatibility.

Paragraph 0035; 0036, (2016/12/26)
The invention discloses a fluorenone nickel pyridine nano-cluster and a method for preparing the same. The fluorenone nickel pyridine nano-cluster and the method have the advantages that fluorenone pyridine organic ligand solution is added into metal salt solution drop by drop, reaction products are ultrasonically dispersed after reaction is completely carried out, are centrifugally separated from one another, are washed and are dried under vacuum conditions to obtain the ligand-metal nano-cluster, procedures for preparing the fluorenone nickel pyridine nano-cluster are simple, and the fluorenone nickel pyridine nano-cluster is low in cost; solvents, the concentration of reactants, the reaction time and the temperatures can be changed, and accordingly the morphology of the fluorenone nickel pyridine nano-cluster can be effectively regulated and controlled; C-C cross coupling reaction can be efficiently catalyzed by the fluorenone nickel pyridine nano-cluster prepared by the aid of the method, the yield can reach 70% at least, and accordingly the fluorenone nickel pyridine nano-cluster can be widely applied to the field of catalysis.
