Abstract:

The purpose of this investigation was to study metal ion complexation of model imides. This was accomplished by observing the effect of metal ion complexation on the carbonyl stretching frequencies of two imides, N-cyclohexyl- N-formlyacetamide and 3,5-dioxopyrrolizidine. Two metal complexes were isolated, CuCl23N-cyclohexyl-N-formylacetamide2 and Co3,5-dioxopyrrolizidine2C104 2. It is concluded on the basis of analyzing the infrared absorption data that when an imide is fixed in a conformation represented by the one for 3,5- dioxopyrrolizidine then chelate formation takes place readily. However, when free rotation around the imide C-N bonds is possible then metal complexation takes place only at one carbonyl and then at the oxygen with the highest electron density.
