Abstract:

Hydrolysis of imines usually leads to the formation of aldehydes. Our research group has previously shown that DyIII can mediate the hydrolysis of Schiff bases in an unusual process to convert imines into acetaldehydes. As a continuation of this work, an uncommon new case of imine hydrolysis, leading to the formation of a carboxylate group, is presented in this communication. The conditions of the media that favour this conversion, which seems again to be mediated by the presence of DyIII , are analysed. The process leads to the formation of a dysprosium complex of formula {[Na2(DyL)2(H2O)8(Et3NH)2(DyL)2}·14H2O. Full characterization of the final product, including single X-ray studies, is reported.

Keywords: Schiff base; carboxylate; hydrolysis; dysprosium(III)
