Switching by Photochemical <i>trans–cis</i> Isomerization of Azobenzene Substituents in Organoplatinum Complexes
Abstract
A diimine ligand, LL = 2-C<sub>5</sub>H<sub>4</sub>NCHN-4-C<sub>6</sub>H<sub>4</sub>NNPh, which carries a <i>trans</i>-azobenzene substituent, forms the dimethylplatinum(II) complex [PtMe<sub>2</sub>(LL)], which undergoes <i>trans</i> oxidative addition with MeI, PhCH<sub>2</sub>Br, Br<sub>2</sub>, and I<sub>2</sub> to give the corresponding organoplatinum(IV) complexes [PtIMe<sub>3</sub>(LL)], [PtBrMe<sub>2</sub>(CH<sub>2</sub>Ph)(LL)], [PtBr<sub>2</sub>Me<sub>2</sub>(LL)], and [PtI<sub>2</sub>Me<sub>2</sub>(LL)], respectively. The ligand and the platinum(II) and platinum(IV) complexes are shown to undergo <i>trans–cis</i> isomerization of the azobenzene substituent upon irradiation, and the <i>cis</i> isomers then underwent slow thermal isomerization back to the more stable <i>trans</i> isomers- Dataset
