Abstract
Cu(Ⅰ)(β-diketonate) 착화합물로서 Cu(Ⅰ)(hfac)PR3(P는 phosphine, R은 Me, Et, Bu를 나타낸다) 착물들을 비수용매에서 유리질 탄소전극과 탄소 microelectrode를 사용하여 이들 착물들의 전기화학적 성질을 조사하였다. 아세토니트릴 용액에서 순환 전압-전류법에 의한 Cu(Ⅰ)(hfac)PR3 착물들의 환원과정은 최종생성물이 Cu(0)로 가는 1전자 반응으로 진행되었다. 탄소 microelectrode를 이용한 대시간-전류법에 의해서 이들 착물들이 1전자 반응으로 진행됨을 확인하였으며, 확산계수는 4.5 ∼ 6.7 × 10-6 cm2/sec값으로 나타났다.

Complexes of Cu(Ⅰ)(hfac)PR3(P: phosphine and R: Me, Et and Bu) as Cu(Ⅰ)(β-diketonate) compounds have been synthesized and their electrochemical properties have been investigated using glassy carbon and carbon microelectrode in aprotic solvent. Reduction process of Cu(Ⅰ)(hfac)PR3 compounds carried out one electron pathway to Cu(0) by cyclic voltammetry in acetonitrile solution. Chronoamperometric curve using carbon microelectrode shows that these complexes are one electron process and diffusion coefficients are 4.5∼6.7 × 10-6 cm2/sec.
