A Facile and Selective SyntheticMethod for the Preparation of Aromatic Dialdehydes from Diesters viathe Amine-Modified SMEAH Reduction System

A new reduction system employing N-methylpiperazine-modified sodium bis(2-methoxyethoxy)aluminum hydride (NMP-SMEAH) for the conversion of aromatic diesters to dialdehydes is described. The method is plain and efficient, and can be carried out under mild and operationally simple conditions applicable for large scale productions.
