Yield:-

Reaction Conditions:

with oxygen in acetonitrile at 120; under 3800.26 Torr; for 13 h;

Steps:

2.3.1. Catalytic experiments
Briefly, the required amount of UiO-66(Zr Ti)-X (X: NH₂, H and NO₂) employed as catalyst (0.016mmol of total metal Zr+Ti) was introduced into a reactor vessel (5mL). Subsequently, the olefin reagent (2mmol) dissolved in CH₃CN (2.5mL) was added to the vessel. The system was pressurized with O₂ at the required value at room temperature (i.e. 5 or 2atm). The reactions were carried out under 600rpm magnetic stirring to ensure that the process is under kinetic control. Catalyst reusability was studied for the most active sample (UiO-66(Zr_5.4Ti_0.6)-NO₂). At the end of the reaction, the solid catalyst was recovered by filtration (Nylon membrane, 0.2μm) and, transferred to a round-bottom flask (50mL) and washed under magnetic stirring with ethanol (20mL) at 80°C for 2h. This procedure was repeated three times. The washed, used solid catalyst was recovered by filtration (Nylon membrane, 0.2μm) and dried in an oven at 100°C for 24h. Before the new catalytic cycle, the solid catalyst was activated at 150°C under vacuum for 16h. Selective radical quenching experiments were carried out following the general reaction procedure described above, but with the addition of radical quenchers (20mol% with respect to the substrate). In particular, dimethylsulfoxide (DMSO) [53-56] or p-benzoquinone [53,54,56,57] were added as selective hydroxyl or superoxide/hydroperoxyl radical scavengers, respectively.
