Many RX compounds enter sluggishly into reaction with magnesium in the preparation of organomagnesium halides. Furthermore, it is actually impossible to form RMgX compounds from some RX compounds. Accordingly, a study is in progress on catalysts and activated magnesium in order to extend the preparation of Grignard reagents. The results so far obtained show that when an alloy containing 121% copper and the remainder magnesium is heated in an evacuated tube at 200° for one hour with about one-half its weight of iodine, the activated alloy thus obtained is superior to that described by Baeyer and used so extensively at present.
