    • The conversion corresponds to the ratio of the sum of imine-type products over the sum of imine-type products plus the sum of the remaining aldehydes (which is equal to the total aldehydes introduced): ∑(imines)/[∑(imines) + ∑(aldehydes)], as directly determined by integration of the corresponding proton NMR signals. The composition is defined as (imine)/∑(imines), and the expression is given by: (imine)/[∑(imines) + ∑(aldehydes)].

    • The system was heated up to 428 K, but above 368 K, unassigned supplementary signals were observed, so that the study was limited to the 298-368 K range.
