Kinetic versus thermodynamic control of the self-assembly of isomeric double-stranded dinuclear titanium(iv) complexes from a phenylalanine-bridged dicatechol ligand

Abstract

The phenylalanine-bridged dicatechol ligand L-H₄ forms under kinetic reaction conditions a double-stranded dinuclear titanium(IV) complex [(L)₂Ti₂(OCH₃)₂]²⁻ , as a mixture of seven regio- and stereo-isomers, which in solution transforms into the thermodynamically favored major product and two minor side products.
