Facile C-H bond activation: synthesis of the N 4 C donor set pentadentate ligand 1,4-bis(2-pyridylmethyl)-1,4-diazacyclononane (dmpdacn) and a structural study of its alkyl?cobalt(III) complex [Co(dmpdacn- C )(OH 2 )](ClO 4 ) 2 ⋅H 2 O and its hydroxylated derivative [Co(dmpdacnOH- O )Cl](ClO 4 ) 2 ⋅C 3 H 6 O

Abstract

The 1,4-bis(2-pyridylmethyl)-1,4-diazacyclononane (dmpdacn) ligand with a N4C donor set deprotonates at a CH2 γ to an amine under extraordinarily mild conditions (pH 7) and binds as a pentadentate ligand to Co(III) as the [Co(dmpdacn-C)(OH2)]2+ complex. Show more
