Abstract

Oxidative addition of H2 and D2 to the anthracene complex (eta6-AnH)Mo(PMe3)3 giving (eta4-AnH)Mo(PMe3)3X2 (X = H, D) is characterized by a normal equilibrium isotope effect (KH/KD > 1) at temperatures close to ambient; calculations on (eta4-AnH)Mo(PH3)3H2 indicate that this is a consequence of relatively low energy Mo-H vibrational modes.

摘要

氢气和氘气向蒽配合物(η⁶ - AnH)Mo(PMe₃)₃的氧化加成反应生成(η⁴ - AnH)Mo(PMe₃)₃X₂(X = H,D),在接近室温的温度下表现出正常的平衡同位素效应(KH/KD > 1);对(η⁴ - AnH)Mo(PH₃)₃H₂的计算表明,这是钼-氢键振动模式能量相对较低的结果。
