| Abstract: | The distribution of nickel in the reaction products from the reactions of nickel(II) stearate with diethylaluminum chloride (Et2AlCl), ethylaluminum sesquichloride (Et3Al2Cl3), and ethylaluminum dichloride (EtAlCl2) in benzene was investigated as a function of the Al/Ni reaction stoichiometry. The products consist of benzene-soluble nickel complexes and a precipitate from which can be extracted NiCl2 and metallic nickel. The percentage of each product is seen to be dependent upon the Al/Ni reaction ratio and the aluminum compound employed in the reaction. It was found that in each case six alkylaluminums are required for complete reaction with one nickel(II) stearate molecule. The compunds Et2AlCl, Et3Al2Cl3, and EtAlCl2 were all found to have greater reducing ability than Et3Al at room temperature. Alternative interpretations of the chloro compounds' greater reducing abilities are discussed. |
