  Abstract

1,2-디클로로에탄에서 [MoO2(S2CNC4H8)2]와 트리페닐포스핀 사이의 산소이동 반응에 대한 속도를 분광학적 방법으로 측정하였다. 514nm 부근에서 흡광도가 시간에 따라 증가하였다가 감소하는데, 이것은 반응의 중간단계에서 몰흡광계수가 큰 [Mo2O3(S2CNC4H8)4]이 생성되었다가 트리페닐포스핀과 더 이상 반응하면 몰리브덴(Ⅳ)가 생성되기 때문이다. 제 1단계에서는 μ-옥소이합체의 생성이, 그리고 제 2단계반응에서는 옥소몰리브덴(Ⅳ)가 생성되는 반응과 관련된 메카니즘이 제시된다. The rates of the reaction Of [MoO2(S2CNC4H8)2] with triphenylphosphine in 1,2-dichloroethane have been by the spectrophotometric method. The increase in absorbance at 514 nm has been interpreted as a result of production of [Mo2O3(S2CNC4H8)4] and the decrease in absorbance then corresponds to the reduction of [Mo2O3(S2CNC4H8)4]. The data suggest mechanisms involving the formation of μ-oxo dimer in the first stage and molybdenum(Ⅳ) in the second stage.
