Discussion.-It seemed that the most promising approach to the problem of preparing an organometallic of a silicon compound (wherein the metal is bonded to silicon) would consist in cleaving an organosilane with a reagent that would leave a metal atom attached to the silicon. A cleaving agent like n-butyllithium is not successful in accomplishing this, since the final product in these cleavages usually has the butyl radical attached to the~ ilicon.~ On ...
