Abstract
Dicyclopentadienyltitanium chloride and bromide prepared in situ from the reduction of dicyclopentadienyltitanium dichloride by isopropylmagnesium chloride and bromide, respectively, are effective dehalogenating reagents for benzylic, allylic halides and α-bromoketones. Benzylic and allylic halides are transformed into the coupling products whereas the α-bromoketones are reduced to the corresponding ketones in satisfactory yields under mild conditions.
