| compound | reaction completed after (h) |
|---|---|
| [MoO(PyS)2(PMe3)2] | 9 |
| [WO(PyS)2(PMe3)2] (3) | 5 |
Conditions: to a 3 mL of CH2Cl2 solution of the [MO(PMe3)2(PyS)2] (0.3 μmol) in a quartz cuvette, 1000 equiv of DMSO was added in the glove box. UV–vis measurement started 3 min after the preparation of the sample. The screening was performed at 25 °C.
