Reactivity of TCNE and TCNQ derivatives of quinonoid zwitterions with Cu(I)
Abstract
<p>The reactions of TCNE- and TCNQ-functionalized (TCNE: tetracyanoethylene and TCNQ: 7,7′,8,8′-tetracyanoquinodimethane) zwitterionic benzoquinonemonoimines with a Cu(i)-BIAN complex (BIAN = bis(o,o′-bisisopropylphenyl)acenaphthenequinonediimine) have been investigated and found to follow a diversity of interesting patterns. The complexes [Cu(BIAN)(NCMe)(L2)]BF<sub>4</sub> (2) and [Cu(BIAN)(L2)<sub>2</sub>]BF<sub>4</sub> (4) were obtained by reacting [Cu(BIAN)(NCMe)<sub>2</sub>]BF<sub>4</sub> (1) with one and two equivalents of L2, respectively. Following similar procedures, the complexes [Cu(BIAN)(NCMe)(L3)]BF<sub>4</sub> (6) and [Cu(BIAN)(L3)<sub>2</sub>]BF<sub>4</sub> (7) were obtained by reaction of 1 with L3. The reaction of 2 with 0.5 equiv. of 4,4′-bipyridine afforded [{Cu(BIAN)(L2)}<sub>2</sub>(μ-4,4′-bipyridine)](BF<sub>4</sub>)<sub>2</sub> (3). The complexes were characterized by multinuclear NMR, IR and UV-Vis spectroscopic techniques, mass spectrometry, cyclic voltammetry and elemental analysis. The molecular structures of complexes 3·4CH<sub>2</sub>Cl<sub>2</sub> and 4·CH<sub>2</sub>Cl<sub>2</sub> were determined by single crystal X-ray diffraction. An unexpected coordination polymer [Cu(L2<sup>-</sup>)<sub>2</sub>]<sub>∞</sub> (5) was also structurally characterized, which contains Cu(ii) centres chelated by two N,O-bound ligands resulting from the monodeprotonation of L2.</p>
