【Abstract】 2,6-diisopropylaniline was treated with eguimolar amounts of n-BuLi and half molar amounts of Me2SiCl2 in sequence.The resulting diamine was treated with n-BuLi and PhCN to give the silyl-linked bis(amidinate) lithium(L).L was partly hydrolyzed to replace half portion lithium ions with hydrogen and then reacted with MnCl2.After recrystallized in toluene-THF mixed solvents with TMEDA donor molecule,the title complex was obtained as colorless crystals,which was characterized by X-ray analysis and elemental analysis.更多还原
