摘要:
SF5Br reacts with 1,2-haloethylenes (F, Cl, Br) in distinct ways. In the case of F- and Cl-olefins, the expected addition occurs while with 1,2-dibromoethylene a metathetical reaction yielding in a clean reaction a 1:1 mixture of SF5CH=CHBr and CHBr2CHBr2 is found. The mechanism for this reaction is discussed. (C) 2008 Elsevier B.V. All rights reserved.
