Can I read Hydrofluorination and Bromofluorination of Halogeno-substituted Ethyl Cinnamates and Related Compounds on EtoBox?
Hydrofluorination and Bromofluorination of Halogeno-substituted Ethyl Cinnamates and Related Compounds by Sylvain Hamman; Claude G. Beguin is a Chemistry article available to read on EtoBox.
What is Hydrofluorination and Bromofluorination of Halogeno-substituted Ethyl Cinnamates and Related Compounds about?
We have effected bromofluorination of six olefins (unsubstituted and a or 6 halogeno-substituted ethyl cinnamates) and ethyl propiolate with N-bromosuccinimide : hydrofluoric acid : pyridine and the hydrofluorination of two t3 halogeno-ethyl cinnamates and ethyl propiolate with hydrofluoric acid : pyridine. The bromofluorination proceeds with Markovnikov-typt regioselectivity and is stereospecific (anti) for unsubstituted and a-halogeno-substituted ethyl cinnamates but faster and not stereospecific for the B-substituted ones and ethyl propiolate. This difference is interpreted for cinnamates as a change in transition state from a bridged bromonium ion to an open-chain ion.
