Preparation And Characterization Of Meridionally Trischelated Rhenium(i) Terpyridine Dicarbonyl Complexes
Abstract
dc:description.abstract<p>Recent work has uncovered a synthetic route to a new series of meridionally coordinated tridentate terpyridine rhenium dicarbonyl complexes. The complex mer,cis-Re(tpy-κ<super>3</super>N)(CO)<sub>2</sub>Cl (1) undergoes facile chloride substitution to produce a variety of complexes of the type mer,cis-[Re(tpy-κ<super>3</super>N)(CO)<sub>2</sub>(L)]n, where L = CF<sub>3</sub>SO<sub>3</sub> (2), CH<sub>3</sub>CN (3), CN (4), NC<sub>5</sub>H<sub>5</sub> (5), PMe<sub>3</sub> (6), PEt<sub>3</sub> (7), PPh<sub>3</sub> (8), P(OMe)<sub>3</sub> (9), P(OEt)<sub>3</sub> (10), P(OPh)<sub>3</sub> (11) ), P(OiPr)<sub>3</sub> (12), P(OMe)(Ph)<sub>2</sub> (13). Complexes 1-13 absorb light throughout a significant portion of the visible spectrum. The electrochemistry of these compounds is discussed in relation to their observed π-acidity and their ability to significantly stabilize the lower oxidation state of rhenium relative to the tricarbonyl bipyridine systems. The complex mer,cis-Re(tpy-κ<super>3</super>N)(CO)<sub>2</sub>Cl (1) produces a first oxidation potential (reversible) that is 0.85 V (vs. SCE) less oxidizing relative to fac-Re(bpy)(CO)<sub>3</sub>Cl's first oxidation potential (irreversible).</p>
