4-Pyridyl-substituted azacycloalkanes with multiple donor sites prepared via a solvent-free, one-pot method for use in electrocatalysts†
Abstract
We report the first, solvent-free synthesis of 4-pyridyl tacn, cyclen, and cyclam derivatives as new design elements to prepare electrocatalysts, for example, by the differential metal complexation of 4-pyncyclen (n = 2, 4).
