摘要：

The rearrangement of beta-ionone in CHBr3 to 1,1,6-trimethyl-1,2,3,4-tetrahydronaphthalene was studied under sonochemical conditions. Trapping experiments showed ultrasound to induce the generation of bromine radicals from CHBr3 that abstracted hydrogen from the solvent to yield HBr. The hydrogen bromide catalyses the cyclisation of beta-ionone.
