Abstract
The redox behavior was evaluated for several (BIPY)Cu(I) complexes (BIPY = 2,2'bipyridyl) with unsatur ated ligands by means of cyclic voltammetry in CH2Cl2 at reduced temperatures (- 78°-;23° 0°C). The complexes studied are [Cu(I)(BIPY)(C2H2)]PF6, [Cu(I)(BIPY)(3-hexyne)]PF6, [Cu(I)(BIPY)(DEAD)]PF6, {[CU(I)(BIPY)]2DEAD}[PF6]2 (DEAD = diethyl acetylene dicarboxylate) and [Cu(I)(BIPY)(CH3CN)]PF6. The oxidations are quasi-reversible at - 78°C for scan rates of 20 to 200mV/sec. The reductions were irreversible on the CV time scale. Evidence is presented in support of a role for an electron transfer mechanism in the case of the plant hormone ethylene. Related literature data are also discussed.
