Reactions of 1,3-diisopropylcarbodiimide with alkali metal amides, MN(SiMe3)2 (M=Li or Na) in hexane or THF produced the alkali metal guanidinates { (i-PrN)2C [N(SiMe3)2]Li }2 (1) and { (i-PrN)2C[N(SiMe3... Reactions of 1,3-diisopropylcarbodiimide with alkali metal amides, MN(SiMe3)2 (M=Li or Na) in hexane or THF produced the alkali metal guanidinates { (i-PrN)2C [N(SiMe3)2]Li }2 (1) and { (i-PrN)2C[N(SiMe3)2]Na(THF) } 2 (2) in nearly quantitative yields. Both complexes 1 and 2 were well characterized by elemental analysis, IR spectra, ^1H and ^13C NMR spectra, and X-ray diffraction. It was found that the guanidinates adopt different coordination modes in these complexes. 展开更多
