Abstract

1412 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim DOI: 10.1002/anie. 200461632 Angew. Chem. Int. Ed. 2005, 44, 1412–1416 temperature. Such mixtures are perfectly stable up to several days. As soon as light or traces of acids initiate the reaction, formation of 1, 2- dibromoethane proceeds very rapidly and autocatalytically (t1/2< 2 min).[1–3] According to the generally accepted mechanism, the stereoselective anti addition of bromine to alkenes ...
