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{(j-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.
