Reaction Conditions:
with C7H13N2O3S(1+)*HO4S(1-)*Cl0.9Nd0.3 in dichloromethane at 37; for 0.75 h;Solvent;Temperature;Reagent/catalyst;
Steps:
10 Example 10
To the three-necked flask was added 10 g of [C3SO3HPy] HSO4 · 0.2MgCl2, 100 g of pseudo-ionone (raw material) and200 g of toluene at 30 ° C for cyclization. After completion of the reaction, the lower ionic liquid layer was separated and washed three times with toluene and washedAfter the ionic liquid can be recycled. Toluene washing solution and the upper reaction liquid combined in the rotary evaporator to separate the toluene, the mostThe target product β-ionone was isolated by distillation under reduced pressure. Raw material conversion rate of 99% or more, β-ionone yield 92%.;Examples 9 - 14Referring to the embodiment 8 of the synthetic method, selecting different under different conditions of the catalyst in the reaction, the obtained conversion and yield are shown in table 2.
