I have read the use of bismuth III oxide perchlorate re arrangement of epoxides posted in Rhodium. ../rhodium /bismuth
swim would like to try the procedure starting with beta- methyl styrene oxide. Has anyone had any experience with the procedure , and can one turn regular styrene into theie beta- methyl styrene oxide in order to keep it OTC in materials. I haven't checked the criteria if Bismuth III oxide perchloride is watched or can be made. According to the litereature the yield is 70% phenylacetone.

You cannot make beta-methylstyrene (propenylbenzene) from regular styrene. The Bi(III) salt is not watched, but it may be classified as toxic.
The propenylbenzene epoxide can be made by oxone oxidation (just like for isosafrole), and another interesting catalyst to be tried is Lithium Iodide in ethyl acetate.
