Molecular thermochemical study of Ni(II), Cu(II) and Zn(II) complexes with N,N′-bis(salicylaldehydo)ethylenediamine

Thermochemical studies on salicylaldehyde and salicylamide

“…In our Research Group, we have been also involved in the study of the energetics of N,N 0 -bis(salicylaldehydo)ethylenediimine (H 2 salen) [1], and of other parent Schiff bases [1,2], derived from salicylaldehyde (2-hydroxybenzaldehyde) with aliphatic or cyclic diamines, as well as some of their first row transition metal complexes [3], since these compounds have an important role on the development of agrochemical and pharmaceutical industries, particularly in the context of catalysis. Although the relevance of salicylaldehyde in the synthesis of the compounds type H 2 salen, the correspondent value for the gaseous enthalpy of formation is not available in the literature.…”

Multigram Mechanochemical synthesis of a Salophen Complex: A Comparative Analysis

“…These species are traditionally obtained from the condensation of salicylaldehydes and diamines 53 under reflux in protic solvents (e.g., methanol, ethanol, etc.). 54 Alternatively, these species can be produced mechanochemically via neat or LAG conditions. 1,15,49,55 In a typical reaction, 5-bromosalicylaldehyde and a diamine (ethylenediamine, and 1, 2-phenylenediamine for salen and salophen ligands, respectively) were ground together in a 15 mL milling jar with an 8 mm diameter ball (both stainless steel); see Figure 3a.…”
