Page/Page column 4; 5; 6, (2012/02/03)
To provide a process for safely producing a perfluoroacyl peroxide with good productivity. By supplying a perfluoroacyl halide-containing organic solvent solution, an aqueous solution of hydrogen peroxide or a metal peroxide, and an aqueous basic alkali metal compound solution to a tubular reactor to allow them to react with one another, in a flow rate ratio of, as represented by molar ratio of the compounds in the solutions, from 1.00 to 1.35 of the basic alkali metal compound and from 0.60 to 40 of hydrogen peroxide or the metal peroxide per 1 of the perfluoroacyl halide, the yield of a perfluoroacyl peroxide based on the material perfluoroacyl halide can be remarkably improved as compared with conventional technique.

Cyclisation of Nb-acetyltryptamines 8 with trifluoracetic anhydride, or pentafluoropropionic anhydride, affords spirocyclic indolines of types 14 and 15 in virtually quantitative yields.The mechanism of the reactions involves cyclisation by ipso-attack at the 3-position of the indole nucleus, to form spirocyclic 3H-indoles 12 and 13, which subsequently undergo addition of the anhydride to the 1,2-double bond of the 3H-indole.The generality of the latter reaction has been established by converting the 3H-indole-3-spirocyclopentane 16 and benzylideneaniline 18 into the anhydride adducts 17a and 19 respectively.The spirocyclic indoline adducts 14a, 14b, 15a, 15b and 17a are rapidly hydrolysed by dilute aqueous ammonia to the hydroxy spirocyclic indolines 20a, 20b, 21a, 21b and 17b respectively.
