Berylliums organo

Of the organometallic compounds of Group II elements, undoubtedly the chemistry of the magnesium compounds is best known. By contrast, the remaining elements in this group have received less attention and it is only recently that more information on organo derivatives of beryllium and, to lesser extent, of calcium, strontium, and barium has become available. Therefore, most of the observations regarding redistribution equilibria have been of more or less qualitative nature.

Organo -Ca, -Sr and -Ba derivatives are prepared from the metals. With Be, however, the compounds are produced from anhydr BeCl2 and organomagnesium-halide reagents or lithium alkyls. In principle, RBe derivatives can also be formed from Be metal. Thus, a Be mirror disappears by the effect of alkyl radicals, but such reactions cannot be used in practice. Beryllium dialkyls also can be prepared from olefins and Hj with the metal in the presence of small amounts of Br2 or I2, and by the electrolysis of M[A1R3R ] complexes (M = Na, K R = alkyl R = alkyl, alkoxy) using anodes of pure Be. However, laboratory application is limited owing to the lack of detailed information and the need for expensive apparatus.
