Abstract
디에탄올아민 디티오카바메이트는 염화디클로로비스(에틸렌디아민)코발트(Ⅲ)와 반응하여 [Co(dtc)3](dtc=디에탄올아민 디티오카바메이트)을 생성한다. 이 때 두 환원자는 코발트에 배위된다. 이 착물은 아세톤에 어느 정도 녹으나 이황화탄소와 같은 비극성 용매에는 거의 녹지 않았다. 디에탄올아민 디티오카바메이트와 염화디클로로비스(에틸렌디아민)코발트(Ⅲ)의 반응 속도를 측정하고 이들 결과에서 얻어진 활성화 파라미터에서부터 가능한 메카니즘을 제시하고자 한다.

Diethanolamine dithiocarbamate is known to react with dichlorobis(ethylenediamine)cohalt(Ⅲ) chloride to form [Co(dtc)3](dtc=diethanolamine dithiocarbamate) in which two sulfur atoms of the dithiocarbamate are bound to cobalt. The complex is moderately soluble in acetone, but sparingly soluble in carbon disulfide. Kinetics and mechanisms of the reaction of dichlorobis(ethylenediamine)cobalt(Ⅲ) chloride with diethanolamine dithiocarbamate have been studied in aqueous solution. Activation parameters have been calculated from the kinetic data for the reaction and from these results a possible mechanism for the reaction has been proposed.
