| 摘 要： | 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.

| Abstract: | 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. |
