Alkenyl bromides by brominative deoxygenation of ketones in one or two steps
Von Roman,Ruhdorfer,Knorr
, p. 985 - 992 (2007/10/02)
The conversion of ketones into alkenyl bromides is accomplished in one or two steps by 2,2,2-tribromo-2,2-dihydro-1,3,2-benzodioxaphosphole or by the dibromomethyl methyl ether prepared therefrom. Investigations of the scope and limitations provide some hints for the preparative planning and improvement.

The cleavage reaction of some 1,3-benzoxathioles with magnesium bromide and acetic anhydride has been studied.In all the 1,3-benzoxathioles studied, the opening of the heterocyclic ring occurs first with cleavage of the C-O bond and formation of bromides and their corresponding products of hydrolysis.Successively also the cleavage of the C-S bond can occur.The competitive electrophilic substitution on the benzene ring becomes appreciable only in the 1,3-benzoxathioles-2,2-disubstituted with sterically demanding groups.The structure of newly prepared compounds has been determined by analytical and spectroscopic data and when possible by comparison with authentic samples.
