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.

A new method for selective reaction of 1-aryl-propane-1-ones with 3,4-dihydroxy group of D-mannitol in the presence of ZnCl2-BF3. Et2O to 3,4-O-(1-aryl-1-propylidene)-D-mannitol (C1-C11) is described. The compounds were first reported and determined by IR, Ms, H-1/C-13 NMR spectra. Among them the structure of C11 was further defined by X-ray diffraction.
