Trichloroisocyanuric Acid: An Alternate Green Route for the Transformation of Alkenes into Epoxides

Autor: Wengert Mira, Sanseverino Antonio M., Mattos Marcio C. S. de

Publikováno v: Journal of the Brazilian Chemical Society, Vol 13, Iss 5, Pp 700-703 (2002)

The preparation of epoxides is efficiently achieved in mild conditions by reaction of alkenes with trichloroisocyanuric acid in aqueous acetone followed by treatment of the resulting chlorohydrin with aqueous KOH in ether / pentane.

Autor: Sanseverino Antonio M., Silva Flavia M. da, Jones Jr Joel, Mattos Marcio C. S. de

Publikováno v: Journal of the Brazilian Chemical Society, Vol 11, Iss 4, Pp 381-386 (2000)

Cohalogenation of (R)-limonene and (R)-carvomenthene with I2/H2O/Cu(OAc)2·H 2O in aqueous dioxane followed by base treatment produced stereospecifically the corresponding trans-epoxides. Same methodology of cohalogenation applied to related monoterp

Hydrobromination of alkenes with PBr3/SiO2: a simple and efficient regiospecific preparation of alkyl bromides

Autor: Sanseverino Antonio M., Mattos Marcio C.S. de

Publikováno v: Journal of the Brazilian Chemical Society, Vol 12, Iss 5, Pp 685-687 (2001)

The reaction of several alkenes with 0.4 mol equiv. PBr3/SiO2 in dichloromethane at room temperature gave the alkyl bromides with Markovnikov regiospecificity in 50 - 100% yield and short reaction time. Isoprene at - 8 °C in these conditions gave 1-
