Reaction Conditions:
with air;Rose Bengal supported on vinylimidazolium-modified Merrifield resin in chloroform at 0; for 1 h;Schlenk technique;Irradiation;
Steps:
Continuous-flow reactions
General procedure: RBPS-vinylimidazolium catalyst(220 mg) were packed into a PTFE tube (ID: 2 mm; OD: 3 mm;L: 10 cm), with in-line filter devices for both ends. This tubewas used as the column for the flow reaction. α-Terpinene wasprepared as the reaction solution in 1,2-dichloroethane (0.1mol/L, kept at 0 °C), with 0.018 mol/L pentadecane as an internalstandard. This mixture (flow rate: 0.02 mL/min) was combinedwith air (0.5 mL/min) and introduced to the column.Three white LED bulbs were used as the light source. The reactionmixture was collected for 1 h and analyzed by GC to determinethe yield.
