在钼化学中, 邻苯醌或1,2-二羰基化合物对钼的氧化加成被广泛应用于钼催化的碳碳成键反应. 其中羰基对零价或者二价钼的协同氧化加成是钼催化的关键基元步骤. 关于该基元步骤的密度泛函理论(DFT)计算研究相对较少, 特别是对泛函的选取缺少参考. 因此, 选择了14种密度泛函计算钼催化的羰基氧化加成过程, 评估了不同泛函对于结构优化和能量计算的准确性. 平均绝对误差(MAE)和平均平方误差(MSE)分析表明, B3LYP-D3(BJ)、TPSSh和ωB97X-D泛函在结构优化方面具有较好的表现. 此外, 基于B3LYP-D3(BJ)泛函在气相中优化得到的结构, 使用M06、M06-L和MN15-L泛函进行能量计算的结果与DLPNO-CCSD(T)泛函计算得到的数据更为接近, 特别是MN15-L的表现最优, 具有最小的MAE和MSE.

In molybdenum chemistry, the oxidative addition of o-quinone or 1,2-dicarbonyl compounds to molybdenum has been widely used in Mo-catalyzed C—C bond construction. The carbonyl oxidative addition to Mo(0) or Mo(II) is the critical elementary reaction of molybdenum catalysis. However, the relevant density functional theory (DFT) studies are relatively scarce, especially regarding the rational selection of functionals. In this work, 14 functionals were employed to investigate the Mo-catalyzed carbonyl oxidative addition step. A benchmark study was carried out to evaluate their performance in structure optimization and energy calculation. Analyses of mean absolute error (MAE) and mean squared error (MSE) indicated that the B3LYP-D3(BJ), TPSSh, and ωB97X-D functionals exhibited superior performance in structure optimization. Using the DLPNO-CCSD(T) functional as the reference, the M06, M06-L, and MN15-L functionals exhibited good performance for energy calculation based on the structures optimized using the B3LYP-D3(BJ) functional. In particular, MN15-L provided the best performance with the smallest MAE and MSE.
