Lithium hydrotri-s-butylborate is shown to be a powerful reducing agent in its reducing abilitie: toward organichalides and discriminates structurally different organichalides due to the bulkiness of the reagent Essentially complete utilization of the hydride of the reagent for the reduction of organichalides is also of synthetic significance.

A new method for the preparation of α-bromoketones from olefins using bromide/bromate couple as a nonhazardous brominating agent has been developed. Several α-bromoketones were successfully prepared from a variety of olefins by this method. This procedure is an alternative to conventional molecular bromine.
